Answer 1

Ответ:

$\frac{22}{265}*5*1=\frac{22}{5}*11=\frac{242}{5}=48,4\\\\ \frac{52}{5}*\frac{27}{9}=\frac{52}{5} *3=\frac{156}{5}=31,2\\\\\frac{11}{27}*9=\frac{11}{3} =3,6\\\\7*\frac{10}{49} =\frac{10}{7}$

Answer 2

Let's calculate each of these expressions step by step:

A) (22/25) * (5 * 11) = (22/25) * 55 = (22 * 55) / 25 = 1210 / 25 = 44.4

B) (5 2/5) * (2 7/9) = To multiply mixed numbers, convert them to improper fractions first.

5 2/5 = (5 * 5 + 2) / 5 = 27/5 2 7/9 = (2 * 9 + 7) / 9 = 25/9

Now, multiply the improper fractions:

(27/5) * (25/9) = (27 * 25) / (5 * 9) = 675 / 45 = 15

C) (11/27) * 9 = (11 * 9) / 27 = 99 / 27 = 11/3

D) 7 * (10/49) = (7 * 10) / 49 = 70 / 49 = 10/7

So, the results are: A) 44.4 B) 15 C) 11/3 D) 10/7
