Answer 24

To subtract 7 1/4 from 8, first convert 8 to a fraction with the same denominator as 7 1/4.

8 is equivalent to 8/1.

To find a common denominator, we multiply 4 by 1 to get 4, then multiply 7 by 4 to get 28.

Now we have 8/1 - 28/4.

To subtract the fractions, we need to find a common denominator. In this case, it is 4.

8/1 can be rewritten as 32/4, since multiplying the numerator and denominator by 4 gives the same value.

Now we have 32/4 - 28/4.

Subtracting the fractions, we get 4/4.

Therefore, 8 - 7 1/4 equals 4/4 or simply 1.

Answer 25

Apologies for the confusion. Let's calculate it again:

To subtract 7 1/4 from 8, we can convert both numbers to fractions with the same denominator.

8 can be converted to 32/4, since 8 equals 32/4.

Now, we have 32/4 - 7 1/4.

To subtract the fractions with the same denominator, we subtract the numerators and keep the denominator the same.

32/4 - 7 1/4 = (32 - 7) / 4 = 25/4.

Therefore, 8 - 7 1/4 equals 25/4 or 6 1/4.

Answer 26

Apologies for the mistake. Let's calculate it correctly this time:

To subtract 7 1/4 from 8, we can convert both numbers to improper fractions.

7 1/4 can be converted to 29/4, since 7 * 4 = 28 and adding 1 gives us 29.

Now, we have 8 - 29/4.

To subtract fractions, we need a common denominator. In this case, it is 4.

8 can be written as 32/4 because 8 * 4 = 32.

Now we have 32/4 - 29/4.

Subtracting the numerators, we get 32 - 29 = 3.

The denominator remains the same, which is 4.

Therefore, 8 - 7 1/4 equals 3/4.

Answer 27

To subtract -4 5/11 from -2 4/11, we need to find a common denominator.

The denominators are already the same (11) in this case.

Now, we can subtract the whole numbers and the fractions separately.

For the whole numbers, -2 - (-4) = -2 + 4 = 2.
For the fractions, 4/11 - 5/11 = -1/11.

Combining these results, we have 2 - 1/11.

Therefore, -4 5/11 - 2 4/11 equals 2 - 1/11, or 1 and 10/11.

Answer 28

Apologies for the mistake. Let's calculate it correctly this time:

To subtract -4 5/11 from -2 4/11, we can first convert both numbers to improper fractions.

-4 5/11 can be written as -49/11, since -4 * 11 = -44 and adding 5 gives us -49.

-2 4/11 can be written as -26/11, since -2 * 11 = -22 and adding 4 gives us -26.

Now, we have -49/11 - (-26/11).

To subtract fractions, we need a common denominator. In this case, it is 11.

Therefore, -49/11 - (-26/11) = -49/11 + 26/11.

By adding the numerators, we get -49 + 26 = -23.

The denominator remains the same, which is 11.

Therefore, -4 5/11 - 2 4/11 equals -23/11.

Converting it to a mixed number, we have -2 1/11.

Answer 29

Apologies for the mistake once again. Let's try to calculate it accurately:

To subtract -4 5/11 from -2 4/11, we can follow these steps:

First, convert both mixed numbers to improper fractions.

-4 5/11 can be written as -49/11, while -2 4/11 can be written as -26/11.

Next, subtract the two fractions:

-49/11 - (-26/11) = -49/11 + 26/11

To add fractions, we need a common denominator, which is 11 in this case.

-49/11 + 26/11 = (-49 + 26)/11 = -23/11

Therefore, -4 5/11 - 2 4/11 equals -23/11.

Answer 30

To subtract -6 7/12 from -4 1/3, we need to find a common denominator.

The denominators are 12 and 3, respectively. The least common multiple of 12 and 3 is 12.

Next, we can convert the mixed numbers to improper fractions.

-6 7/12 can be written as -79/12, since -6 * 12 = -72 and adding 7 gives us -79.

-4 1/3 can be written as -13/3, since -4 * 3 = -12 and adding 1 gives us -13.

Now, we have -79/12 - (-13/3).

To subtract fractions, we need to use the same denominator. In this case, it is 12.

-79/12 - (-13/3) = -79/12 + 52/12.

Adding the numerators, we get -79 + 52 = -27.

The denominator remains the same, which is 12.

Therefore, -6 7/12 - 4 1/3 equals -27/12.

Dividing the numerator and denominator by their greatest common divisor, 3, gives us -9/4.

Therefore, -6 7/12 - 4 1/3 equals -9/4 or -2 1/4.

Answer 31

Apologies for the confusion. Let's calculate it again using fractions:

To subtract -6 7/12 from -4 1/3, we need to find a common denominator.

The denominators are 12 and 3, respectively. The least common multiple of 12 and 3 is 12.

-6 7/12 can be written as -79/12, since -6 * 12 = -72 and adding 7 gives us -79.

-4 1/3 can be written as -13/3, since -4 * 3 = -12 and adding 1 gives us -13.

Now, we have -79/12 - (-13/3).

To subtract fractions, we need to use the same denominator. In this case, it is 12.

-79/12 - (-13/3) = -79/12 + 52/12.

Adding the numerators, we get -79 + 52 = -27.

The denominator remains the same, which is 12.

Therefore, -6 7/12 - 4 1/3 equals -27/12.

Simplifying the fraction, we can divide the numerator and denominator by their greatest common divisor, which is 3.

-27/12 divided by 3/3 equals -9/4.

Therefore, -6 7/12 - 4 1/3 equals -9/4 or -2 1/4.

Answer 39

You're welcome! If you have any more questions, feel free to ask.

Answer 40

To make it easiest to add the expression 18 - 949 + 79 - 8, we should group the terms as follows:

(18 - 8) + (-949 + 79) - 8

This means we first subtract 8 from 18, then add the sum to the sum of -949 and 79, and finally subtract 8.

Therefore, the correct answer is 3. (18 - 8) + (-949 + 79).

Answer 41

The correct answer is 4. Add a zero.

If a place value is missing a number, you should add a zero in that place value to maintain the correct positioning and value of the other digits.

Answer 42

To calculate -18.1 - 5:

-18.1 - 5 = -23.1

Answer 43

To calculate -189.987 - 30.87:

-189.987 - 30.87 = -220.857

Therefore, the answer is 2. -220.857 or negative 220.857.

Answer 44

The correct answer is 1. all functions.

Unicellular cells, as the name suggests, are single-celled organisms. Despite being single-celled, they still need to carry out all the necessary functions of life, such as metabolism, growth, reproduction, and response to stimuli.

Answer 45

The correct answer is 3. A multicellular organism has many specialized cells.

In multicellular organisms, different cells have specific functions and specialize in performing different tasks. This division of labor allows multicellular organisms to carry out a wide range of complex functions and enables greater efficiency in performing specific tasks.

Answer 46

The correct answer is 3. An amoeba is responsible for all functions, and a red blood cell is responsible for some functions.

Amoebas are single-celled organisms that are capable of performing all the necessary functions of life, such as metabolism, growth, reproduction, and response to stimuli.

On the other hand, red blood cells are specialized cells that are responsible for transporting oxygen and carbon dioxide throughout the body. They do not have a nucleus or other organelles and are primarily dedicated to their specific function.

Therefore, amoebas are responsible for all functions, while red blood cells are responsible for a specific function in the body.

Answer 47

The correct answer is 2. A euglena can survive on its own, but a white blood cell cannot.

A euglena is a single-celled organism that is capable of carrying out all necessary life functions on its own, such as movement, reproduction, and obtaining nutrients through photosynthesis or eating other organisms.

On the other hand, a white blood cell is a specialized cell of the immune system that primarily functions within the context of a multicellular organism. White blood cells play a crucial role in defending the body against infections and diseases.

Therefore, a euglena can survive on its own, while a white blood cell requires the support and proper functioning of other cells and systems within the organism.
