1.

1)

$350 \times \frac{6\%}{100\%} = \frac{350 \times 6}{100} = 7 \times 3 = 21$

2)

$120 \times \frac{15\%}{100\%} = \frac{120 \times 15}{100} = 6 \times 3 = 18$

3)

$68 \times \frac{24\%}{100\%} = \frac{68 \times 24}{100} = \frac{68 \times 6}{25} = \\ \frac{408}{25} = 16 \frac{8}{25} = 16.32$

4)

$90 \times \frac{3.5\%}{100\%} = \frac{90 \times 35}{1000} = \frac{9 \times 7}{20} = \\ \frac{63}{20} = 3 \frac{3}{20} = 3.15$

2.

1)

$32 \div \frac{7\%}{100\%} = \frac{32 \times 100}{7} = \frac{3200}{7} = 457 \frac{1}{7}$

2)

$44 \div \frac{12\%}{100\%} = \frac{44 \times 100}{12} = \frac{11 \times 100}{3} = \\ \frac{1100}{3} = 366 \frac{2}{3}$

3)

$162 \div \frac{27\%}{100\%} = \frac{162 \times 100}{27} = 6 \times 100 = 600$

4)

$35 \div \frac{4\%}{100\%} = \frac{35 \times 100}{4} = 35 \times 25 = 875$
