Answer 1

$36.8 \times \frac{5\%}{100\%} = \frac{368}{10 \times 20} = \frac{184}{100} = 1.84$

$128 \times \frac{12.3\%}{100\%} = \frac{128 \times 123}{1000} = \\ \frac{15744}{1000} = 15.744$

$6 \times \frac{11.5\%}{100\%} = \frac{6 \times 115}{1000} = \\ \frac{690}{1000} = 0.69$

$7 \div \frac{1.2\%}{100\%} = \frac{7 \times 1000}{12} = \frac{7 \times 250}{3} = \\ \frac{1750}{3} = 583 \frac{1}{3}$

$2 8\div \frac{5\%}{100\%} = \frac{28 \times 100}{5} = 28 \times 20 = 560$

$12 \div \frac{10.2\%}{100\%} = \frac{12 \times 1000}{102} = \frac{4 \times 500}{17} = \\ \frac{2000}{17} = 117 \frac{11}{17}$
