Question

A rational number is such that when you multiply it by 5/2 and add 2/3 to the product, you get -7/12.What is the number? ​

Answer 1

Step-by-step explanation:

let the rational number be x

then,

(x×5/2)+2/3=-7/12

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

5x/2=(-7-8)/12

5x/2=-15/12

x=-15/12×2/5

x=-1/2(after simplifying)

there fore the required number is -1/2
