1)

$\frac{x}{150} = \frac{50}{100} \\ 100x = 150 \times 50 \\ 100x = 7500 \\ x = 7500 \div 100 \\ x = 75$

2)

$\frac{x}{150} = \frac{30}{100} \\ 100x = 150 \times 30 \\ 100x = 4500 \\ x = 4500 \div 100 \\ x = 45$

3)

$\frac{x}{150} = \frac{10}{100} \\ 100x = 150 \times 10 \\ 100x = 1500 \\ x = 1500 \div 100 \\ x = 15$
