Answer 13

To find the sum of these mixed numbers, we can convert them to improper fractions first.

12 8/15 = 12 + 8/15 = 180/15 + 8/15 = 188/15
7 1/5 = 7 + 1/5 = 35/5 + 1/5 = 36/5

Now we can add:

188/15 - 7 + 36/5 + 15

To add fractions, we need a common denominator. The least common multiple of 15 and 5 is 15, so we can convert 36/5 to an equivalent fraction with a denominator of 15:

36/5 = (36/5) × (3/3) = 108/15

Now we can add:

188/15 - 7 + 108/15 + 15

To subtract 7 from 188/15, we need a common denominator:

188/15 - 7 = 188/15 - 7 × (15/15) = 188/15 - 105/15 = 83/15

Now we can add:

83/15 + 108/15 + 15

To add fractions, we add the numerators and keep the denominator:

(83 + 108)/15 + 15 = 191/15 + 15

To add a fraction and a whole number, we need to convert the whole number to a fraction with a denominator of 15:

15 = 15/1

Now we can add:

191/15 + 15/1 = (191 + 225)/15 = 416/15

Therefore, 12 8/15 - 7 + 7 1/5 + 15 in simplest form is:

416/15

In mixed number form, this is:

27 11/15

Answer 14

Apologies for that! Let's simplify the expression further:

To add the mixed numbers, we need to convert them to improper fractions:

12 8/15 = (12 * 15 + 8) / 15 = 188/15

7 1/5 = (7 * 5 + 1) / 5 = 36/5

Now we can add the fractions:

188/15 - 7 + 36/5 + 15

To subtract 7 from 188/15, we need a common denominator of 15:

188/15 - 7 = 188/15 - 7 * (15/15) = 188/15 - 105/15 = 83/15

Now we can add:

83/15 + 36/5 + 15

To add fractions, we need a common denominator of 15:

83/15 + 36/5 + 15 * (3/3) = 83/15 + 36/5 + 45/3 = 83/15 + 216/15 + 225/15 = (83 + 216 + 225)/15 = 524/15

Therefore, 12 8/15 - 7 + 7 1/5 + 15 in simplest form is:

524/15

In mixed number form, this is:

34 14/15

Answer 15

You're welcome! I'm glad I could help you. If you have any more questions, feel free to ask.

Answer 16

To subtract a mixed number from a whole number, we must first convert the mixed number to an improper fraction.

7 1/4 can be written as the improper fraction: (7 * 4 + 1) / 4 = 29/4.

Now we can subtract:

8 - 29/4

To subtract fractions, we need a common denominator. The common denominator here is 4, so we need to convert 8 to a fraction with a denominator of 4:

8 = 8/1.

Now we can subtract:

8/1 - 29/4.

To subtract fractions, we need the same denominator:

8/1 - 29/4 = (32/4) / (1/4) - 29/4 = (32 - 29) / 4 = 3/4.

Therefore, 8 - 7 1/4 as a fraction is 3/4.

Answer 17

To subtract fractions, we need a common denominator. In this case, the denominators are already the same (11), so we can subtract the fractions directly:

4 5/11 - 2 4/11

First, let's convert the mixed numbers to improper fractions:

4 5/11 = (4 * 11 + 5) / 11 = 49/11
2 4/11 = (2 * 11 + 4) / 11 = 26/11

Now, we can subtract the fractions:

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

Therefore, 4 5/11 - 2 4/11 as a fraction is 23/11.

Answer 18

Apologies for the misunderstanding. To subtract the fractions 4 5/11 - 2 4/11, we need to find a common denominator and then subtract the numerators.

The common denominator is 11, so we can rewrite the fractions with this denominator:

4 5/11 = (4 * 11 + 5)/11 = 49/11
2 4/11 = (2 * 11 + 4)/11 = 26/11

Now we can subtract the fractions:

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

Therefore, the difference 4 5/11 - 2 4/11 as a fraction is 23/11.

Answer 19

To subtract decimal numbers, we align the decimal points and subtract as usual:

907.907
- 709.709
----------
198.198

Therefore, 907.907 - 709.709 equals 198.198.

Answer 20

To subtract decimal numbers, we align the decimal points and subtract as usual:

90.897
- 81.725
----------
9.172

Therefore, 90.897 - 81.725 equals 9.172.

Answer 21

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

Answer 22

To subtract mixed numbers, we first convert them to improper fractions and then subtract the fractions.

-6 7/12 can be written as -(6 * 12 + 7) / 12 = -79/12

-4 1/3 can be written as -(4 * 3 + 1) / 3 = -13/3

Now we can subtract the fractions:

-79/12 - (-13/3)

To subtract fractions, we need a common denominator. The least common multiple of 12 and 3 is 12:

-79/12 - (-13/3) = -79/12 + 52/12 = (-79 + 52)/12 = -27/12

Now, we can simplify the fraction:

-27/12 = -9/4

Therefore, -6 7/12 - 4 1/3 as a fraction is -9/4.

Answer 23

Math can sometimes be perceived as difficult because it requires logical thinking, problem-solving skills, and understanding of concepts and formulas. Additionally, math often builds upon previously learned concepts, so if there are any gaps in understanding, it can create challenges.

However, with the right approach and practice, math can become more manageable. Breaking down problems into smaller steps, seeking help from teachers or tutors, practicing regularly, and developing a positive mindset towards math can all contribute to improving math skills.

It's important to remember that everyone learns at their own pace, and it's natural to face challenges in various subjects, including math. With perseverance and a growth mindset, you can overcome difficulties and develop a stronger understanding and appreciation for math.

Answer 25

To subtract mixed numbers, we first convert them to improper fractions and then subtract the fractions.

-4 5/11 can be written as -(4 * 11 + 5) / 11 = -49/11

-2 4/11 can be written as -(2 * 11 + 4) / 11 = -26/11

Now we can subtract the fractions:

-49/11 - (-26/11)

To subtract fractions, we simply subtract the numerators while keeping the common denominator:

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

Therefore, -4 5/11 - 2 4/11 as a fraction is -23/11.
