Question

a rational number is such that when we multiply it by 10upon3 and add 3upon8 to the product we get minus3upon2. what is the number ​

Answer 1

Step-by-step explanation:

let the no. be x

ATQ

10/3x + 3/8 = -3/2

10/3x = -3/2 - 3/8

10/3x = (-12-3)/8

10/3x = -15/8

x= -15/8 * 3/10

x= -3/8 * 3/2

x= -9/16

Answer 2

Step-by-step explanation

Let the rational no.be x.

A.T.Q.

10/3*x+3/8=-3/2

(80x+9)/24=-3/2

2(80x+9)=-3*24

2(80x+9)=-72

80x+9=-72/2

80x+9=-36

80x=-36-9

80x=-45

x=-1/2
