Let’s solve each problem step by step. We’re adding fractions, and the picture shows us what the total should look like — so we can use that to figure out the missing fraction.
Remember: When you add two fractions with the same denominator (bottom number), you just add the numerators (top numbers). The denominator stays the same.
Also, the pictures show how many parts are shaded in total — that tells us the answer fraction. Then we subtract the first fraction from the total to find the second one.

Problem 1:
Given: 2/6 + ? = pizza with 5 slices shaded out of 6 → 5/6
So: 2/6 + ? = 5/6
→ Missing numerator = 5 - 2 = 3
Answer: 3/6

Problem 2:
First fraction: 3/10
Picture: chocolate cake with 7 slices shaded out of 10 → 7/10
So: 3/10 + ? = 7/10
→ Missing numerator = 7 - 3 = 4
Answer: 4/10

Problem 3:
First fraction: 4/8
Picture: rectangle with 6 blue squares out of 8 → 6/8
So: 4/8 + ? = 6/8
→ Missing numerator = 6 - 4 = 2
Answer: 2/8
---
Problem 4:
First fraction: 1/5
Picture: pizza with 4 slices shaded out of 5 → 4/5
So: 1/5 + ? = 4/5
→ Missing numerator = 4 - 1 = 3
Answer: 3/5
---
Problem 5:
First fraction: 2/7
Picture: circle with 4 pink slices out of 7 → 4/7
So: 2/7 + ? = 4/7
→ Missing numerator = 4 - 2 = 2
Answer: 2/7

Problem 6:
First fraction: 5/9
Picture: orange circle with 8 slices shaded out of 9 → 8/9
So: 5/9 + ? = 8/9
→ Missing numerator = 8 - 5 = 3
Answer: 3/9
---
Problem 7:
First fraction: 6/10
Picture: pink rectangle with 9 squares shaded out of 10 → 9/10
So: 6/10 + ? = 9/10
→ Missing numerator = 9 - 6 = 3
Answer: 3/10
---
Problem 8:
First fraction: 3/6
Picture: pizza with 5 slices shaded out of 6 → 5/6
So: 3/6 + ? = 5/6
→ Missing numerator = 5 - 3 = 2
Answer: 2/6

Problem 9:
First fraction: 2/8
Picture: rectangle with 5 blue squares out of 8 → 5/8
So: 2/8 + ? = 5/8
→ Missing numerator = 5 - 2 = 3
Answer: 3/8

Problem 10:
First fraction: 4/9
Picture: orange circle with 7 slices shaded out of 9 → 7/9
So: 4/9 + ? = 7/9
→ Missing numerator = 7 - 4 = 3
Answer: 3/9
