Question

A reational number is such that when you multiple it by 5/2 and add 2/3 to the product you get -7/12. What is the number.

Answer 1

Answer:

-1/2

Step-by-step explanation:

let that rational number be X

x*5/2 = 5x/2

according to question, we add 2/3 to product

5x/2 + 2/3 = 15x + 4 /6

15x+4/6 = -7/12

180x + 48 = -42

180x = -42 - 48

180x = -90

x = -90/180

x = -1/2

-1/2 is the correct answer of the given question.
