Question

1. Аяна решает б примеров за одну минуту. За какое время Аяна решит 72 примера? ​

Answer 1

Ответ:

12 мин

Пошаговое объяснение:

6 примеров - 1 мин

72 примера - х мин

х=1×72:6=12 мин

Answer 2

Ответ:

За 12 минут.

Пошаговое объяснение:

72:6=12

Потому, что если она решает 6 примеров в минуту, то за 12 минут она сможет решить 72.

Answer 3

To find out the time it takes for Ayana to solve 72 problems, we need to know the rate at which she solves problems per minute. The rate is given as "b" problems per minute.

Let's assume that Ayana solves "b" problems in one minute. Therefore, in x minutes, she would solve x * b problems.

We can set up a proportion to solve the problem:

b problems / 1 minute = 72 problems / x minutes

Using cross-multiplication, we have:

b * x = 72 * 1

Simplifying, we get:

bx = 72

To find x, we divide both sides by b:

x = 72 / b

Therefore, Ayana will solve 72 problems in (72 / b) minutes.
