Answer 12

To simplify the given expression, we can add the rational numbers together.

125.06 + 0.47 + 36

To add rational numbers, we need to align the decimal points and then add the numbers:

125.06
+ 0.47
+ 36.00
_________
= 161.53

Answer 13

To evaluate the expression, we first need to convert the mixed numbers into improper fractions:

6 9/10 - 4 3/10 - 1/10

= (6*10 + 9)/10 - (4*10 + 3)/10 - 1/10

= (69/10) - (43/10) - (1/10)

Next, we can combine the numerator terms and keep the denominator the same:

= (69 - 43 - 1)/10

= 25/10

Since 25 is divisible by 5 and 10, we can simplify the fraction:

= 5/2

Therefore, the expression 6 9/10 - 4 3/10 - 1/10 is equal to 5/2.

Answer 14

Apologies for the mistake. Let's redo the calculation:

To evaluate the expression, we need to subtract the given rational numbers:

6 9/10 - 4 3/10 - 1/10

First, convert the mixed numbers into improper fractions:

(6*10 + 9)/10 - (4*10 + 3)/10 - 1/10

= (69/10) - (43/10) - (1/10)

Next, combine the numerator terms:

= (69 - 43 - 1)/10

= (25/10)

Since 25 is divisible by 5 and 10, we can simplify the fraction:

= (5 * 5)/(2 * 5)

= 5/2

Therefore, the expression 6 9/10 - 4 3/10 - 1/10 is equal to 5/2, which is the same as 2 1/2.

Answer 15

To evaluate the expression -14.6 - 12.8 + (-12.8), we simply add or subtract the numbers in order:

-14.6 - 12.8 + (-12.8)

= -27.4 + (-12.8)

Combining the two negative numbers:

= -27.4 - 12.8

Now we can add the numbers:

= -40.2

Therefore, the expression -14.6 - 12.8 + (-12.8) is equal to -40.2.

Answer 16

Apologies for the mistake. Let's redo the calculation:

To evaluate the expression -14.6 - 12.8 + (-12.8), we need to add or subtract the numbers in order:

-14.6 - 12.8 + (-12.8)

First, let's combine the negative numbers:

-14.6 + (-12.8) + (-12.8)

Next, add the positive and negative numbers:

= -14.6 - 12.8 - 12.8

Now we can add the numbers:

= -40.2

Therefore, the expression -14.6 - 12.8 + (-12.8) is equal to -40.2, which matches the option -40.2.

Answer 17

Apologies for the confusion. Let's go through the calculation again:

To evaluate the expression -14.6 - 12.8 + (-12.8), we need to add or subtract the numbers in order:

-14.6 - 12.8 + (-12.8)

Let's combine the negative numbers:

= -14.6 + (-12.8) + (-12.8)

Now we can add the numbers:

= -14.6 + (-12.8) + (-12.8)

= -14.6 - 12.8 - 12.8

= -40.2

Therefore, the expression -14.6 - 12.8 + (-12.8) is equal to -40.2, which is not one of the given options. Apologies for the incorrect information provided earlier, and thank you for bringing it to my attention.

Answer 18

To simplify the given expression, we need to find a common denominator for the fractions and combine all the terms:

-3 + 4/7 - 1/5

First, let's find a common denominator for 7 and 5, which is 35.

= (-3 * 35/35) + (4/7 * 5/5) - (1/5 * 7/7)

= -105/35 + 20/35 - 7/35

Now we can combine the terms with the same denominator:

= (-105 + 20 - 7)/35

= -92/35

Therefore, the simplified expression -3 + 4/7 - 1/5 is equal to -92/35.

Answer 19

To simplify the expression -3 + 4/7 - 1/5, let's find a common denominator for 7 and 5, which is 35:

-3 + 4/7 - 1/5 = -3 * 35/35 + 4/7 * 5/5 - 1/5 * 7/7

This simplifies to:

-105/35 + 20/35 - 7/35 = (-105 + 20 - 7)/35 = -92/35

Now, let's convert the improper fraction -92/35 into a mixed number:

-92 ÷ 35 = -2 remainder 22

Therefore, the simplified expression -3 + 4/7 - 1/5 is equivalent to -2 22/35, which matches the option -2 22/35.

Answer 20

Thank you for confirming! If you have any more questions, feel free to ask.

Answer 21

To simplify the expression 3/5 + 1 1/5 - 2/5, we need to convert the mixed number (1 1/5) to an improper fraction.

First, let's convert 1 1/5 to an improper fraction:

1 1/5 = (1 * 5 + 1)/5 = 6/5

Now, let's rewrite the expression with the improper fraction:

3/5 + 6/5 - 2/5

Since the denominators are the same for all fractions, we can add the numerators directly:

(3 + 6 - 2)/5 = 7/5

So, the simplified expression 3/5 + 1 1/5 - 2/5 is equal to 7/5.

Answer 22

To convert the improper fraction 7/5 to a mixed number, we divide the numerator (7) by the denominator (5):

7 ÷ 5 = 1 remainder 2

So the mixed number is 1 2/5.

Therefore, the simplified expression 3/5 + 1 1/5 - 2/5 is equal to 1 2/5.

Answer 23

To simplify the given expression, we need to find a common denominator for the fractions and then add them together.

The common denominator for 4 and 7 is 28.

Now, let's rewrite the fractions with the common denominator:

25/4 + 33/7 + 39/4

= (25 * 7/7 * 4) + (33 * 4/4 * 7) + (39 * 7/7 * 4)

= 175/28 + 132/28 + 273/28

Now, we can add the fractions:

= (175 + 132 + 273)/28

= 580/28

Finally, we can simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 4:

= 145/7

Therefore, the simplified expression 25/4 + 33/7 + 39/4 is equal to 145/7.
