Answer:

1. $\frac{4}{7}$

2. $\frac{39}{14}$ or 2 $\frac{11}{14}$

3. $\frac{484}{15}$ or 32 $\frac{4}{15}$

4. $\frac{96}{35}$ or 2 $\frac{26}{35}$

Explanation:

There are 3 simple steps to multiply fractions

(always convert mixed fraction to improper fraction first)

1. Multiply the top numbers (the numerators).

2. Multiply the bottom numbers (the denominators).

3. Simplify the fraction if needed.

EXAMPLES:

1. $\frac{3}{4}$ x $\frac{16}{21}$

Step 1: Multiply the top numbers (the numerators)

3 x 16 = 48 (48 is the new numerator)

Step 2: Multiply the bottom numbers (the denominators)

4 x 21 = 84 (84 is the new denominator)

Step 3: Simplify

Since $\frac{48}{84}$ is the new fraction, it can be simplified as $\frac{4}{7}$

Answer: $\frac{4}{7}$

2. 5 $\frac{7}{9}$ x $\frac{27}{56}$ (5 $\frac{7}{9}$ = $\frac{52}{9}$ )

Step 1: Multiply the top numbers (the numerators)

52 x 27 = 1404 (1404 is the new numerator)

Step 2: Multiply the bottom numbers (the denominators)

9 x 56 = 504 (504 is the new denominator)

Step 3: Simplify

Since $\frac{1404}{504}$ is the new fraction, it can be simplified as $\frac{39}{14}$ or 2 $\frac{11}{14}$

Answer: $\frac{39}{14}$ or 2 $\frac{11}{14}$

3. 4 $\frac{2}{5}$ x 7 $\frac{1}{3}$ (4 $\frac{2}{5}$ = $\frac{22}{5}$ ) and (7 $\frac{1}{3}$ = $\frac{22}{3}$ )

Step 1: Multiply the top numbers (the numerators)

22 x 22 = 484 (484 is the new numerator)

Step 2: Multiply the bottom numbers (the denominators)

5 x 3 = 15 (15 is the new denominator)

Step 3: Simplify

Since $\frac{484}{15}$ is the new fraction, it can be simplified as 32 $\frac{4}{15}$

Answer: 32 $\frac{4}{15}$
