Answer 1

b)

$\frac{2x}{25}=\frac{6}{9} \\ \frac{2x}{5} = \frac{2}{3} \\ 6x = 10$

$x = \frac{10 \div 2}{6 \div {2}} = \frac{5}{3}$

c)

$\frac{x - 2}{12 \div 4} = \frac{x}{20 \div 4} \\ \frac{x - 2}{3} = \frac{x}{5} \\ 5x - 10 = 3x$

$5x - 3x = 10 \\ 2x = 10 \\ x = \frac{10}{2} = 5$

d)

$\frac{x + 1}{5} = \frac{x}{3} \\ 5x = 3x + 3 \\ 5x - 3x = 3 \\ 2x = 3$

$x= \frac{3}{2}$

e)

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

f)

$\frac{6}{7 \div 7} = \frac{3x}{28 \div 7} \\ 6 = \frac{3x}{4} \\ 3x = 24$

$x = \frac{24}{3} = 8$
