Question

A rational number is such that when we multiply it by 10/3 and add 3/8 to product we get -3/2.what is the number

Answer 1

hope you have got it

Answer 2

let the rational no. be x

$x( \frac{10}{3}) = \frac{10x}{3} + \frac{3}{8} = \frac{ - 3}{2}$

taking LCM,

$\frac{80x + 9}{24} = \frac{ - 3}{2}$

on cross multiplication,

$80x + 9 = - 36$

$80x = - 36 - 9$

$80x = - 45$

$x = - \frac{ - 9}{16}$
