Question

The sum of two rarional number is 3/5 .If one of them is -2/7 find the other

Answer 1

Answer:

Let another rational number be X.

According to question

3/10 + X = -3/5

3 + 10X/10 = -3/5

5 ( 3 + 10X ) = -30

15 + 50X = -30

50X= -30-15

50X = -45

X= -45/50 = -9/10

Hence,

-9/10 should b added to 3/10 to get -3/5.
