Answer 2

Answer:

The required solution of x$=20$

Step-by-step explanation:

In accordance with the information provided in the question,

Given the data in question 5 by 7 = x by 28

We can write ,

$\frac{5}{7} =\frac{x}{28}$

We have find the value of x in the above question.

Here we will use the transposition method.

Arrange the equation and  cross  multiplication (5into 28) and (x into 7)

We get,

$5\times28=x\times7\\140=7x$

We can write this $7x=140$

Dividing both side by 7 we get,

$\frac{7x}{7} =\frac{140}{7}$

Simplifying further we get,

$x=20$

Hence the required solution of x$=20$
