Worksheet for practicing subtraction of fractions with like denominators.

Sure! Let’s solve the worksheet titled “SUBTRACT FRACTIONS WITH LIKE DENOMINATORS”.

---

✔ Key Concept:

When subtracting fractions with like denominators, you simply:
> Subtract the numerators and keep the same denominator.

Then, simplify the fraction if possible (reduce to lowest terms).

Let’s go problem by problem:

---

1)  $\frac{3}{7} - \frac{2}{7} = \frac{1}{7}$

→ Numerators: 3 - 2 = 1; Denominator stays 7. Already simplified.

---

2)  $\frac{3}{5} - \frac{1}{5} = \frac{2}{5}$

→ 3 - 1 = 2 → $\frac{2}{5}$

---

3)  $\frac{8}{9} - \frac{5}{9} = \frac{3}{9} = \frac{1}{3}$

→ 8 - 5 = 3 → $\frac{3}{9}$ simplifies to $\frac{1}{3}$ (divide numerator & denominator by 3)

---

4)  $\frac{7}{8} - \frac{4}{8} = \frac{3}{8}$

→ 7 - 4 = 3 → $\frac{3}{8}$ (already simplified)

---

5)  $\frac{4}{5} - \frac{3}{5} = \frac{1}{5}$

→ 4 - 3 = 1 → $\frac{1}{5}$

---

6)  $\frac{8}{10} - \frac{3}{10} = \frac{5}{10} = \frac{1}{2}$

→ 8 - 3 = 5 → $\frac{5}{10}$ simplifies to $\frac{1}{2}$

---

7)  $\frac{9}{5} - \frac{3}{5} = \frac{6}{5} = 1\frac{1}{5}$

→ 9 - 3 = 6 → $\frac{6}{5}$ is an improper fraction → convert to mixed number: $1\frac{1}{5}$

*(Note: Some worksheets may accept improper fractions unless specified otherwise. But since this is elementary level, mixed numbers are often preferred.)*

---

8)  $\frac{11}{12} - \frac{7}{12} = \frac{4}{12} = \frac{1}{3}$

→ 11 - 7 = 4 → $\frac{4}{12}$ simplifies to $\frac{1}{3}$

---

9)  $\frac{18}{20} - \frac{11}{20} = \frac{7}{20}$

→ 18 - 11 = 7 → $\frac{7}{20}$ (already simplified)

---

10)  $\frac{8}{7} - \frac{4}{7} = \frac{4}{7}$

→ 8 - 4 = 4 → $\frac{4}{7}$

---

11)  $\frac{11}{20} - \frac{4}{20} = \frac{7}{20}$

→ 11 - 4 = 7 → $\frac{7}{20}$

---

12)  $\frac{11}{12} - \frac{5}{12} = \frac{6}{12} = \frac{1}{2}$

→ 11 - 5 = 6 → $\frac{6}{12}$ simplifies to $\frac{1}{2}$

---

13)  $\frac{14}{15} - \frac{8}{15} = \frac{6}{15} = \frac{2}{5}$

→ 14 - 8 = 6 → $\frac{6}{15}$ simplifies to $\frac{2}{5}$ (divide by 3)

---

14)  $\frac{14}{15} - \frac{11}{15} = \frac{3}{15} = \frac{1}{5}$

→ 14 - 11 = 3 → $\frac{3}{15}$ simplifies to $\frac{1}{5}$

---

15)  $\frac{7}{10} - \frac{3}{10} = \frac{4}{10} = \frac{2}{5}$

→ 7 - 3 = 4 → $\frac{4}{10}$ simplifies to $\frac{2}{5}$

---

16)  $\frac{12}{16} - \frac{6}{16} = \frac{6}{16} = \frac{3}{8}$

→ 12 - 6 = 6 → $\frac{6}{16}$ simplifies to $\frac{3}{8}$ (divide by 2)

---

17)  $\frac{11}{20} - \frac{7}{20} = \frac{4}{20} = \frac{1}{5}$

→ 11 - 7 = 4 → $\frac{4}{20}$ simplifies to $\frac{1}{5}$

---

18)  $\frac{27}{30} - \frac{18}{30} = \frac{9}{30} = \frac{3}{10}$

→ 27 - 18 = 9 → $\frac{9}{30}$ simplifies to $\frac{3}{10}$ (divide by 3)

---
