Printable worksheet for practicing fraction multiplication to the 12ths.

Let's solve each of these fraction multiplication problems step by step. The general rule for multiplying fractions is:

$$
\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}
$$

We'll simplify where possible before or after multiplying.

Column 1

1. $\frac{8}{11} \times \frac{5}{6} = \frac{8 \times 5}{11 \times 6} = \frac{40}{66} = \frac{20}{33}$
(Simplify: divide numerator and denominator by 2)

2. $\frac{3}{4} \times \frac{4}{5} = \frac{3 \times 4}{4 \times 5} = \frac{12}{20} = \frac{3}{5}$
(Cancel 4 in numerator and denominator, then simplify)

3. $\frac{1}{9} \times \frac{6}{8} = \frac{1 \times 6}{9 \times 8} = \frac{6}{72} = \frac{1}{12}$
(Simplify: divide by 6)

4. $\frac{1}{5} \times \frac{3}{4} = \frac{3}{20}$
(No simplification needed)

5. $\frac{9}{9} \times \frac{3}{6} = 1 \times \frac{1}{2} = \frac{1}{2}$
($\frac{9}{9} = 1$, $\frac{3}{6} = \frac{1}{2}$)

6. $\frac{1}{5} \times \frac{3}{4} = \frac{3}{20}$
(Same as #4)

7. $\frac{10}{10} \times \frac{2}{2} = 1 \times 1 = 1$

8. $\frac{9}{10} \times \frac{6}{8} = \frac{9 \times 6}{10 \times 8} = \frac{54}{80} = \frac{27}{40}$
(Divide numerator and denominator by 2)

9. $\frac{4}{10} \times \frac{7}{10} = \frac{28}{100} = \frac{7}{25}$
(Simplify: divide by 4)

10. $\frac{2}{6} \times \frac{2}{2} = \frac{1}{3} \times 1 = \frac{1}{3}$
($\frac{2}{6} = \frac{1}{3}$, $\frac{2}{2} = 1$)

Column 2

11. $\frac{2}{2} \times \frac{5}{6} = 1 \times \frac{5}{6} = \frac{5}{6}$

12. $\frac{3}{5} \times \frac{1}{8} = \frac{3}{40}$

13. $\frac{5}{9} \times \frac{1}{8} = \frac{5}{72}$

14. $\frac{8}{10} \times \frac{7}{12} = \frac{4}{5} \times \frac{7}{12} = \frac{28}{60} = \frac{7}{15}$
(Simplify: divide by 4)

15. $\frac{3}{4} \times \frac{3}{5} = \frac{9}{20}$

16. $\frac{3}{4} \times \frac{2}{4} = \frac{6}{16} = \frac{3}{8}$

17. $\frac{2}{5} \times \frac{5}{5} = \frac{2}{5} \times 1 = \frac{2}{5}$

18. $\frac{1}{12} \times \frac{2}{8} = \frac{1}{12} \times \frac{1}{4} = \frac{1}{48}$

19. $\frac{2}{2} \times \frac{2}{6} = 1 \times \frac{1}{3} = \frac{1}{3}$

20. $\frac{6}{10} \times \frac{1}{3} = \frac{3}{5} \times \frac{1}{3} = \frac{3}{15} = \frac{1}{5}$

Column 3

21. $\frac{5}{8} \times \frac{12}{12} = \frac{5}{8} \times 1 = \frac{5}{8}$

22. $\frac{3}{4} \times \frac{2}{2} = \frac{3}{4} \times 1 = \frac{3}{4}$

23. $\frac{2}{2} \times \frac{3}{9} = 1 \times \frac{1}{3} = \frac{1}{3}$

24. $\frac{3}{4} \times \frac{8}{12} = \frac{3}{4} \times \frac{2}{3} = \frac{6}{12} = \frac{1}{2}$
($\frac{8}{12} = \frac{2}{3}$, then cancel 3s)

25. $\frac{7}{10} \times \frac{3}{3} = \frac{7}{10} \times 1 = \frac{7}{10}$

26. $\frac{5}{12} \times \frac{4}{4} = \frac{5}{12} \times 1 = \frac{5}{12}$

27. $\frac{1}{6} \times \frac{3}{8} = \frac{3}{48} = \frac{1}{16}$

28. $\frac{2}{2} \times \frac{6}{7} = 1 \times \frac{6}{7} = \frac{6}{7}$

29. $\frac{2}{12} \times \frac{1}{8} = \frac{1}{6} \times \frac{1}{8} = \frac{1}{48}$

30. $\frac{11}{11} \times \frac{1}{3} = 1 \times \frac{1}{3} = \frac{1}{3}$

📝 Summary Tips:

- Always look for simplifications before multiplying (cancel common factors).
- Remember that $\frac{a}{a} = 1$, so any fraction multiplied by a whole number over itself becomes the other fraction.
- Reduce final answers to lowest terms.
