Answer 1

$1) \: 35 \times \frac{x}{100} = 21 \\ = 60 \\ 2) \: 80 \times \frac{x}{100} = 4 \\ = 5 \\ 3) \: \frac{x}{100} \times 300 = 450 \\ = 150 \\ 4) \: 50 \times \frac{x}{100} = 15 \\ = 30 \\ 5) \: 15 \times \frac{x}{100} = 30 \\ = 200 \\ 6) \: 20 \times \frac{x}{100} = 16.6 \\ = 83$

All answers are in percentage.
