Answer 1

Explicación paso a paso:

$b) \\ \frac{1}{8} a = \frac{21}{4} \\ \\ a = \frac{21}{4} \div \frac{1}{8} \\ \\ a = \frac{168}{4} \\ \\ a = 42$

$a ) \\ \frac{1}{7}x = 49 \\ \\ x = 49 \div \frac{1}{7} \\ \\ x = 343$

$c) \\ \frac{2}{3} a = \frac{21}{4} \\ \\ a = \frac{21}{4} \div \frac{2}{3} \\ \\ a = \frac{63}{8}$

$d) \\ \frac{3}{8} = x \times \frac{1}{5} \\ \\ \frac{3}{8} \div \frac{1}{5} = x \\ \\ \frac{15}{8} = x$

$e) \\ \frac{9}{10} x = \frac{9}{100} \\ \\ x = \frac{9}{100} \div \frac{9}{10} \\ \\ x = \frac{90}{900} \\ \\ x = \frac{1}{10}$

$f) \\ \frac{5}{7} x = \frac{10}{14} \\ \\ x = \frac{10}{14} \div \frac{5}{7} \\ \\ x = \frac{70}{70} \\ \\ x = 1$
