Question

What should be added to 2 / 7 to
get 9 / 14.​

Answer 1

Answer:

5/14

Step-by-step explanation:

let the number to be added be x

so 2/7 +x = 9/14

= x = 9/14-2/7

= x= 9/14 - (2×2/7×2)

= x= 9/14-4/14 (because LCM=14)

= x= (9-4)/14

= x= 5/14

so the number to be added to 2/7 to get 9/14 is 5/14
