Answer 1

Explicación paso a paso:

a)

$\frac{1}{7} x = 49$

$\frac{x}{7} = 49$

$x = 49(7)$

$x = 343$

b)

$\frac{1}{8} n = \frac{5}{2}$

$\frac{n}{8} = \frac{5}{2}$

$2n = 5(8)$

$2n = 40$

$n = \frac{40}{2}$

$n = 20$

c)

$\frac{2}{3} a = \frac{21}{4}$

$(4)2a = 21( 3)$

$8a = 63$

$a = \frac{63}{8}$

$a = 7.9$

d)

$\frac{3}{8} = x \frac{1}{5}$

$3(5) = x(8)$

$15 = 8x$

$\frac{15}{8} = x$

$1.9 = x$

e)

$\frac{9}{10} = m \frac{9}{100}$

$9(100) = 9m(10)$

$900 = 90m$

$\frac{900}{90} = m$

$10 = m$

f)

$\frac{5}{7} = \frac{10}{14} x$

$5(14) = 10x(7)$

$70 = 70x$

$\frac{70}{70} = x$

$1 = x$

g)

$\frac{3}{7} = \frac{4}{9} a$

$3(9) = 4a(7)$

$27 = 28a$

$\frac{27}{28} = a$

$0.96 = a$

h)

$\frac{2}{5} = \frac{4}{30} b$

$2(30) = 4b(5)$

$60 = 20b$

$\frac{60}{20} = b$

$3 = b$
