Question

what should be added to-3/7 to get 4/9 an?​

Answer 1

Answer:

7/36

Step-by-step explanation:

Let the number that should be added to be x.

therefore 1/4 + x = 4/9

x = 4/9 – 1/4

LCM of 9 and 4 = 9 × 4 = 36

= x = (4 × 4)/(9 × 4) – (1 × 9)/(4 × 9)

= x = 16/36 – 9/36

= x = 7/36

So, 7/36 must be added to 1/4 to get 4/9.
