2) 19/2 × 19/19

Q) Divide
1) 11/24 by 7/8
2) 18/5 ÷ 4/5​

Answer 1

Answer:

1)

$\frac{5}{12}$

2)

$9 \frac{1}{2}$

3)

$\frac{11}{28}$

4)

$4 \frac{1}{2}$

Step-by-step explanation:

1)

$\frac{4}{9} \times \frac{15}{16} \\ = \frac{1}{3} \times \frac{5}{4} \\ = \frac{5}{12}$

2)

$\frac{19}{2} \times \frac{19}{19} \\ = \frac{19}{2} \times 1 \\ = \frac{19}{2} \\ = 9 \frac{1}{2}$

3)

$\frac{11}{24} \div \frac{7}{8} \\ = \frac{11}{24} \times \frac{8}{7} \\ = \frac{11}{4} \times \frac{1}{7} \\ = \frac{11}{28}$

4)

$\frac{18}{5} \div \frac{4}{5} \\ = \frac{18}{5} \times \frac{5}{4} \\ = \frac{9}{1} \times \frac{1}{2} \\ = \frac{9}{2} \\ = 4 \frac{1}{2}$
