Question

The sum of rational numbers is 5/7 one of them is 3/4 find the other

Answer 1

Answer:

The other number is - 1/28

Step-by-step explanation:

Let x be the other rational number.

x + 3/4 = 5/7

x = 5/7-3/4

=[5x4 -3x7]/28

=-1/28

Answer 2

Answer:

Another Number is -1/28

Step-by-step explanation:

let

another number be x

and, another number be 3/4

Sum of both rational number = 5/7

so,

3/4 + x = 5/7

x = 5/7 - 3/4

LCM = 28

x = 20/28 - 21/28

x = 20 - 21 / 28

x = -1 / 28
