a) $\frac{15}{4} = \frac{30}{x}$

$15x = 120$

$x=8$

b) $\frac{3}{5} = \frac{x}{10}$

$5x=30$

$x=6$

c) $\frac{1}{x} =\frac{9}{3}$

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

d) $\frac{x}{15} =\frac{1}{5}$

$5x=15$

$x=3$

e) $\frac{x}{9} =\frac{3}{1}$

$x=27$

f) $\frac{x}{2} =\frac{15}{10}$

$2x=6$

$x=3$

g) $\frac{5}{y} =\frac{3}{6}$

$x=10$

h) $\frac{7}{8} =\frac{14}{a}$

$7x=112$

$x=16$

i) $\frac{x}{5} =\frac{21}{33}$

$x=\frac{35}{11}$

j) $\frac{4x}{3} =\frac{16}{6}$

$12x=24$

$x=2$
