Answer 1

f)

$\frac{ 6}{4 + 6} = \frac{x}{20} \\ \\ \frac{6}{10} = \frac{x}{20} \\ \\ 10x = 120 \\ \\ x = 20 \div 10 = 12$

$\frac{6}{4} = \frac{12}{y} \\ \\ 6y = 48 \\ \\ y = 48 \div 6 = 8$

i)

$\frac{y}{4} = \frac{6}{8} \\ \\ 8y = 24 \\ \\ y = 24 \div 8 = 3$

$\frac{2.5}{3} = \frac{x}{6} \\ \\ 3x = 15 \\ \\ x = 15 \div 3 = 5$
