Question

What number should be subtracted from 3/7 to get 5/4?​

Answer 1

Solution:

Let us consider a number as x to be subtracted from 3/7 to get 5/4

So, 3/7 – x = 5/4

x = 3/7 – 5/4

let us take LCM for 7 and 4 which is 28

x = (3×4 – 5×7)/28

= (12 – 35)/28

= -23/28

∴ the required number is -23/28

Answer 2

Answer:

-23/28

Step-by-step explanation:

Let the number be x

3/7 - x = 5/4

x = 3/7 - 5/4

x= 12/28 - 35/28

x = -23/28
