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

Let say Number  = A

we multiply it by 10 upon 3

=> 10A/3

add 3 upon 8 to the products

=> 10A/3  + 3/8

= (80A + 9)/24

we get minus 3 upon 2

=> (80A + 9)/24 = -3/2

=> 80A + 9 = -36

=> 80A = -45

=> 16A = - 9

=> A = -9/16

number is -9/16
