Question

The sum of two rational numbers is 2/5.if one of them is -4/7, then find the other

Answer 1

Step-by-step explanation:

Let the other number be x.

According to the question:-

→ x + -4/7 = 2/5

→ x - 4/7 = 2/5

→ x = 2/5 + 4/7

Now, find the LCM of 5 and 7, i.e 35.

→ x = (14 + 20)/35

→ x = 34/35

Therefore, the value of the other rational number is 34/35.

Answer 2

Answer:

x+(-4/7=2/5

x-4/7=2/5

x=2/5+4/7

x=(2×7+4×5)7×5

x=(14+20/35

x=34/35
