What is 12 8/15 − 7 + 71/5 + 15? Simplify your answer.

Answer 1

We can first simplify the expression 12 8/15 by multiplying the whole number part (12) by the denominator of 15 and adding the numerator (12 * 15 + 8 = 188). So the expression becomes 188/15 - 7 + 71/5 + 15.

Now, we need to find a common denominator for the fractions. We can use the least common multiple (LCM) of 15 and 5, which is 15.

Converting the fractions to have a denominator of 15:
188/15 - (7 * 15)/15 + (71 * 3)/15 + (15 * 15)/15
188/15 - 105/15 + 213/15 + 225/15

Combining the fractions:
(188 - 105 + 213 + 225) / 15
(301 + 438) / 15
739 / 15

So, the simplified answer is 739/15.

Answer 2

Use

21

20 15/15

35

41 15/15

Answer 3

To simplify the expression, we combine the whole numbers and the fractions separately.

Whole numbers: 21 + 35 + 41 = 97

Fractions: 20 15/15 = 20 + (15/15) = 20 + 1 = 21

Now we add the whole numbers and fractions: 97 + 21 = 118.

Thus, the simplified answer is 118.
