Answer 1

А)$( \frac{3*4-11}{15} )* \frac{5}{11}$=$\frac{1}{15} * \frac{5}{11}$=$\frac{5}{165} = \frac{1}{31}$
б)$\frac{7}{88} * ( \frac{8+3*8}{21} )= \frac{7}{88} * \frac{32}{21} = \frac{224}{1848} = \frac{4}{33}$
в)$( \frac{3+7}{12}) * \frac{3}{7} = \frac{5}{6} * \frac{3}{7} = \frac{15}{42}$

Answer 2

Calculation of Expression (a)

To find the value of the expression (4/5 - 11/15) * 5/11, we can follow the order of operations (PEMDAS/BODMAS) and simplify step by step.

1. Simplify the subtraction inside the parentheses: 4/5 - 11/15 = (12/15) - (11/15) = 1/15

2. Multiply the result by 5/11: (1/15) * (5/11) = 5/165

Therefore, the value of the expression (4/5 - 11/15) * 5/11 is 5/165.

Calculation of Expression (b)

To find the value of the expression 7/88 * (8/21 + 8/7), we can again follow the
