Question

The sum of two rational numbers is -3/5 ,if one of the numbers is -9/20 . find other

Answer 1

Answer:

Rational numbers:

• Rational numbers are the numbers that are in the form of p/q where p and q are integers and q is not equal to zero.

Given:

We have been given that the sum of two rational numbers is -3/5 and one among them is -9/20.

To Find:

We need to find the other rational number.

Solution:

Let the other rational number be x.

As it is given that the sum of two rational numbers is-3/5, so

x + (-9/20) = -3/5

=> x - 9/20 = -3/5

=> x = -3/5 + 9/20

Taking LCM as 20, we get

x = -12/20 + 9/20

=> x = (-12+9)/20

=> x = -3/20

Therefore the second rational number is -3/20.

Answer 2

Solutions:

Let the other rational number be x.

Given that;

The sum of two rational number is -3/5.

x = ( -9/20) = -3/5

x - 9/20 = -3/5

x = -3/5 + 9/20

x = -12/20 + 9/20

x = -3/20

Thus, the 2nd rational no. is -3/20.
