Answer 1

Esas son las respuestas con sus respectivos procedimientos

1.

$\frac{15}{8} \times 9 = \frac{15 \times 9}{8 \times 1} = \frac{135}{8}$

2.

$\frac{12}{5} \times \frac{10}{9}$

Simplificar las fracciones

$\frac{12}{5} \times \frac{10}{9} = 4 \times \frac{2}{3} = \frac{4 \times 2}{1 \times 3} = \frac{8}{3}$

3.

$\frac{6}{25} \div \frac{12}{5} = \frac{6 \times 5}{25 \times 12} = \frac{30}{300} = \frac{3}{30} = \frac{1}{10}$

4.

$\frac{10}{21} \times \frac{5}{6} \times 4 \\ = \frac{5}{21} \times \frac{5}{3} \times 4 \\ = \frac{5 \times 5 \times 4}{21 \times 3 \times 1} \\ = \frac{100}{63}$

5.

$\frac{16}{15} \times \frac{10}{9} \times \frac{3}{8} \\ = \frac{4}{3} \times \frac{1}{3} \times 1 \\ = \frac{4 \times 1\times 1}{3 \times 3 \times 1} \\ = \frac{4}{9}$

6.

$\frac{10}{1} \div \frac{4}{3} \times \frac{7}{5} \\ = \frac{10 \times 3}{1 \times 4} \times \frac{7}{5} = \frac{30}{4} \times \frac{7}{5} \\ = \frac{15}{2} \times \frac{7}{5} = \frac{3}{2} \times 7 \\ = \frac{3 \times 7}{2 \times 1} = \frac{21}{2}$
