Let’s solve each problem one by one. We’re adding fractions that have the same bottom number (denominator). When denominators are the same, we just add the top numbers (numerators) and keep the denominator the same.

Problem 1:
We have:
> 2/9 + 2/9
Add the numerators: 2 + 2 = 4
Keep the denominator: 9
So, answer is
4/9
Check: The circles show 2 shaded parts out of 9 in each — together that’s 4 out of 9. Makes sense!
---
Problem 2:
> 1/4 + 1/4
Add numerators: 1 + 1 = 2
Denominator stays 4 → 2/4
But wait — can we simplify? Yes! 2/4 = 1/2
(If you split a circle into 4 and shade 2, it’s half the circle.)
So, answer is
1/2

Problem 3:
> 3/10 + 4/10
Add numerators: 3 + 4 = 7
Denominator stays 10 →
7/10
Check: 3 purple slices + 4 purple slices = 7 out of 10 total slices. Correct!
---
Problem 4:
> 1/3 + 1/3
Add numerators: 1 + 1 = 2
Denominator stays 3 →
2/3
Check: Each circle has 1 out of 3 shaded — together that’s 2 out of 3. Perfect.
---
Problem 5:
> 2/12 + 8/12
Add numerators: 2 + 8 = 10
Denominator stays 12 → 10/12
Can we simplify? Yes! Both 10 and 12 can be divided by 2.
10 ÷ 2 = 5
12 ÷ 2 = 6
So, 10/12 =
5/6
Check: 2 red slices + 8 red slices = 10 out of 12 — which is the same as 5 out of 6 if you group them. Good!

Final Answer:
1) 4/9
2) 1/2
3) 7/10
4) 2/3
5) 5/6
