Question

Teach me..How to do this.. Okay​

Answer 1

Step-by-step explanation:

Let the no added be x.

a/q

5 3/7 + x = 20

38/7 + x = 20

Transpose 38/7 to rhs

x = 20/1 - 38/7

Take lcm of denominators

x = 140/7 - 38/7

x = 102/7 or 14 4/7

Answer 2

Hi,

Solution-

The sum of the numbers=20

Given number=5 3/7=[(5*7)+3]/7=38/7

Let the other number be 'i'.

ATQ,

38/7+i=20

⇒i=20-38/7

⇒i=140-38/7

⇒i=102/7

102/7 is the answer.
