Answer 1

Answer:

$(i) \: \frac{3}{4} \times \frac{5}{6} = \frac{3 \times 5}{4 \times 6} = \frac{1\times 5}{4 \times 2} = \frac{5}{8} \\\\</p><p></p><p> \frac{3}{4} \div \frac{5}{6} \\= \frac{3}{4} \times \frac{6}{5} \\= \frac{3 \times 6}{4 \times 5}</p><p>\\= \frac{3 \times 3}{2 \times 5}</p><p></p><p> \\ = \frac{9}{10} </p><p></p><p></p><p>\\ \\ (ii) \: total \: part \: of \: the \: book \: read \\ \: \: \: \: \: \: \: = \frac{1}{2} + \frac{1}{3} \\\: \: \: \: \: \: \: = \frac{1 \times 3 + 1 \times 2}{2 \times 3} \\ \: \: \: \: \: \: \: = \frac{3 + 2}{6} \\ \: \: \: \: \: \: \: = \frac{5}{6} \\ remainig \: part of \: the \: book\: to \: be \: \\ read = 1 - \frac{5}{6} = \frac{6 - 5}{6} = \frac{1}{6}$
