Question

The product of two rational numbers is 10/3 if one of the number is -4/15 ,find the other number

Answer 1

Given:

The product of two rational numbers is 10/3 if one of the numbers is -4/15

To find:

The other number.

Solution:

1) Rational numbers are the number which can be represented in p/q form where p and q are integers and q must not be equal to zero.

2) Let other number is a

according to the question:

• (-4/15)×a = 10/3

• a = (10/3)÷(-4/15)

• a = (10/3)×(-15/4)

• a = -25/2

The other rational number is -25/2

Answer 2

Answer:

let the no. be x

(-4/5) × x = (10/3)

x = (10/3) ÷ (-4/5)

x = (10/3) × (-5/4)

x= (-25/6)
