25. Simplify the following:

We’ll simplify each expression one by one.

#### a) $\frac{9}{10} \times 15$

$$
\frac{9}{10} \times 15 = \frac{9 \times 15}{10} = \frac{135}{10} = 13.5 \quad \text{or} \quad \frac{27}{2} = 13\frac{1}{2}
$$

✔ Answer: $13\frac{1}{2}$

---

#### b) $20 \times \frac{10}{25}$

Simplify $\frac{10}{25} = \frac{2}{5}$

$$
20 \times \frac{2}{5} = \frac{40}{5} = 8
$$

✔ Answer: 8

---

#### c) $3 \times \frac{7}{10}$

$$
\frac{3 \times 7}{10} = \frac{21}{10} = 2\frac{1}{10}
$$

✔ Answer: $2\frac{1}{10}$

---

#### d) $\frac{5}{3} \times \frac{9}{13}$

$$
\frac{5 \times 9}{3 \times 13} = \frac{45}{39} = \frac{15}{13} = 1\frac{2}{13}
$$

✔ Answer: $1\frac{2}{13}$

---

#### e) $\frac{13}{5} \times \frac{5}{26}$

Cancel common factors:

- 5 in numerator and denominator cancel.
- 13 and 26: $26 = 2 \times 13$, so cancel 13.

$$
\frac{13}{5} \times \frac{5}{26} = \frac{1}{1} \times \frac{1}{2} = \frac{1}{2}
$$

✔ Answer: $\frac{1}{2}$

---

#### f) $\frac{12}{10} \times \frac{7}{21}$

Simplify fractions:

- $\frac{12}{10} = \frac{6}{5}$
- $\frac{7}{21} = \frac{1}{3}$

Now:

$$
\frac{6}{5} \times \frac{1}{3} = \frac{6}{15} = \frac{2}{5}
$$

✔ Answer: $\frac{2}{5}$

---

#### g) $8 \times 4\frac{1}{6}$

Convert mixed number to improper:

$4\frac{1}{6} = \frac{25}{6}$

$$
8 \times \frac{25}{6} = \frac{200}{6} = \frac{100}{3} = 33\frac{1}{3}
$$

✔ Answer: $33\frac{1}{3}$

---

#### h) $3\frac{3}{7} \times 1\frac{1}{7}$

Convert both to improper:

- $3\frac{3}{7} = \frac{24}{7}$
- $1\frac{1}{7} = \frac{8}{7}$

$$
\frac{24}{7} \times \frac{8}{7} = \frac{192}{49} = 3\frac{45}{49}
$$

✔ Answer: $3\frac{45}{49}$

---

#### i) $9 \text{ of } \frac{6}{15}$

"Of" means multiplication.

$$
9 \times \frac{6}{15} = \frac{54}{15} = \frac{18}{5} = 3\frac{3}{5}
$$

✔ Answer: $3\frac{3}{5}$

---

#### j) $5 \text{ of } \frac{15}{25}$

$$
5 \times \frac{15}{25} = 5 \times \frac{3}{5} = 3
$$

✔ Answer: 3

---

#### k) $1\frac{2}{3} \times 3\frac{4}{5}$

Convert to improper:

- $1\frac{2}{3} = \frac{5}{3}$
- $3\frac{4}{5} = \frac{19}{5}$

$$
\frac{5}{3} \times \frac{19}{5} = \frac{95}{15} = \frac{19}{3} = 6\frac{1}{3}
$$

✔ Answer: $6\frac{1}{3}$

---

#### l) $3\frac{1}{3} \times 12$

Convert: $3\frac{1}{3} = \frac{10}{3}$

$$
\frac{10}{3} \times 12 = \frac{120}{3} = 40
$$

✔ Answer: 40
