Let's solve each problem step by step and match it with the correct answer from the right column.
---
a) ³⁄₂₀ + ⁷⁄₂₀ =
Since the denominators are the same, we add the numerators:
3 + 7 = 10 → so the result is
¹⁰⁄₂₀
Simplify: divide numerator and denominator by 10 →
¹⁄₂
✔ Match:
¹⁄₂
---
b) ⁴⁄₅ - ²⁄₃ =
Different denominators. Find LCD of 5 and 3 →
15
Convert fractions:
⁴⁄₅ = (4×3)/(5×3) =
¹²⁄₁₅
²⁄₃ = (2×5)/(3×5) =
¹⁰⁄₁₅
Now subtract: ¹²⁄₁₅ - ¹⁰⁄₁₅ =
²⁄₁₅
✔ Match:
²⁄₁₅
---
c) ¹⁄₁₀ + ⁴⁄₅ =
Different denominators. LCD of 10 and 5 is
10
Convert ⁴⁄₅ to tenths: ⁴⁄₅ = (4×2)/(5×2) =
⁸⁄₁₀
Now add: ¹⁄₁₀ + ⁸⁄₁₀ =
⁹⁄₁₀
✔ Match:
⁹⁄₁₀
---
d) ⁷⁄₁₁ - ¹⁄₂ =
LCD of 11 and 2 is
22
Convert:
⁷⁄₁₁ = (7×2)/(11×2) =
¹⁴⁄₂₂
¹⁄₂ = (1×11)/(2×11) =
¹¹⁄₂₂
Subtract: ¹⁴⁄₂₂ - ¹¹⁄₂₂ =
³⁄₂₂
✔ Match:
³⁄₂₂
---
e) ²⁄₅ × ⁵⁄₆ =
Multiply numerators: 2 × 5 = 10
Multiply denominators: 5 × 6 = 30
→
¹⁰⁄₃₀
Simplify: divide numerator and denominator by 10 →
¹⁄₃
✔ Match:
¹⁄₃
---
f) ⁶⁄₉ ÷ ³⁄₄ =
To divide fractions, multiply by the reciprocal:
⁶⁄₉ × ⁴⁄₃
First, simplify ⁶⁄₉ → divide numerator and denominator by 3 →
²⁄₃
So now: ²⁄₃ × ⁴⁄₃ = (2×4)/(3×3) =
⁸⁄₉
✔ Match:
⁸⁄₉
---
✔ Final Matching Answers:
a) ³⁄₂₀ + ⁷⁄₂₀ →
¹⁄₂
b) ⁴⁄₅ - ²⁄₃ →
²⁄₁₅
c) ¹⁄₁₀ + ⁴⁄₅ →
⁹⁄₁₀
d) ⁷⁄₁₁ - ¹⁄₂ →
³⁄₂₂
e) ²⁄₅ × ⁵⁄₆ →
¹⁄₃
f) ⁶⁄₉ ÷ ³⁄₄ →
⁸⁄₉
You can now drag and drop the correct boxes to match each problem.
