Question

A rational number is such that when you multiply it by 2/5 and add 2/3 to the product , you get 7/15 .What is the rational number?​

Answer 1

Answer:

According to the given information.

We consider the term x to be the required answer.

Therefore x*(5/2)

Then add it to 2/3 to give - 7/12

So, x*(5/2) +(2/3) = - 7/12

5x/2 = - 7/12 - 2/3

5x/2 = - 15/12

5x = - 30/12

x = - 6/12

x = - 1/2

So the required answer is - 1/2.

Answer 2

Given:

A rational number is such that when we multiply it by 2/5 and add 2/3 to the product, we get 7/15.

To find:

The rational number

Solution:

x*(2/5) + (2/3) = 7/15

2x/5 =  7/15 - 2/3

2x/5 = - 9/45

2x/5 = - 1/5

x = - 1/2

Hence, the rational number is - 1/2.
