Question

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

Answer 1

Answer:

10/6 is the answer mate

Answer 2

x = -17/15

Step-by-step explanation:

Hi,

let the rational numbers be x

Therefore,

5/2 × x = 5x/2

Now according to the question

5x/2 + 2/3 = 7/2

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

5x/2 =(4 - 21) /6

5x/2 = -17/6

(6 × 5x) /2 = -17

3 × 5x = -17

15x = -17

x = -17/15
