Question

A) 7/11(дробь) от a = 35 a=b) 0,6 от b = 42 b =(Варианты)0,0670,670

Answer 1

Ответ:

70

Пошаговое объяснение:

а) 7/11*а=35

а=35*11/7

а=55

b) 6/10*a=42

b=42*10/6

b=70

Answer 2

Let's solve the given equations step by step:

A) $\frac{7}{11}$ of $a$ is equal to 35:

Let's represent the given statement as an equation: $\frac{7}{11} \times a = 35$

To find the value of $a$, we can isolate $a$ by multiplying both sides of the equation by the reciprocal of $\frac{7}{11}$, which is $\frac{11}{7}$: $a = 35 \times \frac{11}{7}$ $a = 55$

So, $a = 55$.

B) $0.6$ of $b$ is equal to 42:

Let's represent the given statement as an equation: $0.6 \times b = 42$

To find the value of $b$, we can isolate $b$ by dividing both sides of the equation by $0.6$: $b = \frac{42}{0.6}$ $b = 70$

So, $b = 70$.

Therefore, the correct value of $b$ is $b = 0.670$.
