Answer 1

Ответ:

Пошаговое объяснение:

(2 2/7*×):7 1/2=3 3/4​

2 2/7x : 7 1/2 = 3 3/4

2 2/7x = 3 3/4 * 7 1/2

2 2/7x = 15/4 * 15/2

2 2/7x = 30/8

x = 30/8 : 16/7

x = 30/8 * 7/16

x = 15/8 * 7/8

x = 105/64

x = 1 41/64

Ответ: 1 41/64.

Answer 2

It looks like you're trying to solve a mathematical expression involving fractions and multiplication. Let's break it down step by step:

The expression is: (2 2/7) × 7 1/2 = 3 3/4

First, let's convert the mixed numbers into improper fractions: 2 2/7 = (2 * 7 + 2) / 7 = 16 / 7 7 1/2 = (7 * 2 + 1) / 2 = 15 / 2

So the expression becomes: (16/7) × (15/2)

Now, multiply the fractions: (16/7) × (15/2) = (16 * 15) / (7 * 2) = 240 / 14 = 120 / 7

Now, let's convert the fraction 120/7 into a mixed number: Divide 120 by 7: 120 ÷ 7 = 17 with a remainder of 1

So, 120/7 is equivalent to the mixed number 17 1/7.

Now let's compare the result with the given expression: 3 3/4

It seems like there might be an error or misunderstanding in the original expression since 17 1/7 is not equal to 3 3/4.

Please double-check the original expression or let me know if there's a specific question you have related to this calculation.
