Question

(9-2 3/11)+(2+1 9/11) по действиям

Answer 1

$1)9 - 2 \frac{3}{11} = 8 \frac{11}{11} - 2 \frac{3}{11} = 6 \frac{8}{11} \\ 2)2 + 1 \frac{9}{11} = 3 \frac{9}{11} \\ 3)6 \frac{8}{11} + 3 \frac{9}{11} = 9 + \frac{8}{11} + \frac{9}{11} = 10 \frac{7}{11}$

Answer 2

To perform the given arithmetic expression, let's start by simplifying the mixed fractions first:

9 - 2 3/11 = 6 8/11 2 + 1 9/11 = 3 9/11

Now, the expression becomes:

(6 8/11) + (3 9/11)

Next, let's add the whole numbers together and then the fractions separately:

Whole numbers: 6 + 3 = 9

Fractions: 8/11 + 9/11 = 17/11

Now, we have 9 as the whole number and 17/11 as the fraction, but we need to simplify it further. We can rewrite 17/11 as a mixed fraction:

17/11 = 1 6/11

Now, the expression becomes:

9 + 1 6/11

Adding the whole number and the fraction:

9 + 1 = 10

So, the result of the expression is 10.
