Answer 1

E)

$\frac{35}{25} = \frac{30}{x} \\ 35x = 750 \\ \ x = \frac{750}{35} \\ x = \frac{150}{7}$

F)

$\frac{2x}{15} = \frac{6}{9} \\ 18x = 90 \\ x = \frac{90}{18} \\ x = 5$

G)

$\frac{2x}{3} = \frac{8}{6} \\ 12x = 24 \\ x = \frac{24}{12} \\ x = 2$

H)

$\frac{6}{7} = \frac{3x}{28} \\ 21x = 168 \\ x = \frac{168}{21} \\ x = 8$
