Question

What is the sum of 7/22 and 9/22

Answer 1

 when u have a common a denominator then you just add the numerator that would be 7 and 9. 7 + 9= 16
so ur solution would be 16/22 and then u would simplify by dividing both values by 2.
so the solution is8/11

Answer 2

You need a common denominator. You already have one. So add 7+9=16. Put 16 over 22. That's your answer without reduction.

When you reduce it, divide it by 2 since its an even number.

16/22=8/11
