Step-by-step solution for: Multiplying Mixed Fractions
Let's solve each problem step by step. The goal is to multiply mixed fractions, convert them to improper fractions, multiply, and simplify the result (leaving it as an improper fraction if needed, but in simplest form).
---
1. Convert mixed numbers to improper fractions.
2. Multiply the two improper fractions.
3. Simplify the result (reduce if possible).
4. Leave as an improper fraction unless otherwise specified.

$$
2\frac{2}{5} \times \frac{2}{3} = \frac{12}{5} \times \frac{2}{3} = \frac{24}{15} = \frac{8}{5}
$$
Now let’s solve each problem.
---
Convert $ 2\frac{1}{2} $:
$ 2 + \frac{1}{2} = \frac{4}{2} + \frac{1}{2} = \frac{5}{2} $
Now multiply:
$$
\frac{5}{2} \times \frac{4}{5} = \frac{5 \times 4}{2 \times 5} = \frac{20}{10} = 2
$$
✔ Answer: 2
---
Convert $ 1\frac{3}{4} $:
$ 1 + \frac{3}{4} = \frac{4}{4} + \frac{3}{4} = \frac{7}{4} $
Multiply:
$$
\frac{7}{4} \times \frac{3}{5} = \frac{21}{20}
$$
This is already simplified.
✔ Answer: $ \frac{21}{20} $
---
Convert $ 4\frac{1}{2} $:
$ 4 + \frac{1}{2} = \frac{8}{2} + \frac{1}{2} = \frac{9}{2} $
Multiply:
$$
\frac{9}{2} \times \frac{5}{6} = \frac{45}{12}
$$
Simplify $ \frac{45}{12} $: divide numerator and denominator by 3 → $ \frac{15}{4} $
✔ Answer: $ \frac{15}{4} $
---
Convert $ 2\frac{2}{7} $:
$ 2 + \frac{2}{7} = \frac{14}{7} + \frac{2}{7} = \frac{16}{7} $
Now multiply by 3:
$$
\frac{16}{7} \times 3 = \frac{16 \times 3}{7} = \frac{48}{7}
$$
✔ Answer: $ \frac{48}{7} $
---
Convert $ 3\frac{1}{5} $:
$ 3 + \frac{1}{5} = \frac{15}{5} + \frac{1}{5} = \frac{16}{5} $
Multiply:
$$
\frac{2}{7} \times \frac{16}{5} = \frac{32}{35}
$$
Already simplified.
✔ Answer: $ \frac{32}{35} $
---
Convert $ 8\frac{1}{2} $:
$ 8 + \frac{1}{2} = \frac{16}{2} + \frac{1}{2} = \frac{17}{2} $
Multiply:
$$
\frac{17}{2} \times \frac{2}{11} = \frac{34}{22}
$$
Simplify: divide numerator and denominator by 2 → $ \frac{17}{11} $
✔ Answer: $ \frac{17}{11} $
---
Convert $ 4\frac{2}{3} $:
$ 4 + \frac{2}{3} = \frac{12}{3} + \frac{2}{3} = \frac{14}{3} $
Multiply:
$$
\frac{5}{12} \times \frac{14}{3} = \frac{70}{36}
$$
Simplify: divide numerator and denominator by 2 → $ \frac{35}{18} $
✔ Answer: $ \frac{35}{18} $
---
Convert both:
- $ 2\frac{1}{5} = \frac{10}{5} + \frac{1}{5} = \frac{11}{5} $
- $ 5\frac{1}{2} = \frac{10}{2} + \frac{1}{2} = \frac{11}{2} $
Multiply:
$$
\frac{11}{5} \times \frac{11}{2} = \frac{121}{10}
$$
Already simplified.
✔ Answer: $ \frac{121}{10} $
---
1) $ \boxed{2} $
2) $ \boxed{\frac{21}{20}} $
3) $ \boxed{\frac{15}{4}} $
4) $ \boxed{\frac{48}{7}} $
5) $ \boxed{\frac{32}{35}} $
6) $ \boxed{\frac{17}{11}} $
7) $ \boxed{\frac{35}{18}} $
8) $ \boxed{\frac{121}{10}} $
All answers are in simplest form as improper fractions, as requested.
