Question

15 7/10+2 2/10-4 1/10

Answer 1

Ответ:

13 13/20

$15 \frac{7}{10} + 2 \frac{2}{10} - 4 \frac{1}{4} =$

$(15 + 2 - 4) + ( \frac{7}{10} + \frac{2}{10} - \frac{1}{4} )$ =

$13 + \frac{13}{20} = 13 \frac{13}{20}$

Answer 2

To solve this arithmetic expression, you need to perform addition and subtraction of mixed numbers:

15 7/10 + 2 2/10 - 4 1/10

First, let's add the two mixed numbers:

15 7/10 + 2 2/10 = 17 9/10

Now, subtract the third mixed number:

17 9/10 - 4 1/10 = 13 8/10 = 13 4/5

So, the result of the expression is 13 4/5.
