Answer 1

Answer:

According to your question

we have to solve the questions given above.

$1. \: \: 12 \div \frac{3}{4} \\ \\ = \geqslant 12 \times \frac{4}{3} \\ \\ = \geqslant \: we \: can \: change \: divide \: sign \\ into \: multiply \: sign \: just \: by \: revering \\ the \: denominator \: into \: numerator \\ and \: vis \: versa \\ \\ = \geqslant 12 \times \frac{4}{3} \\ \\ = \geqslant 4 \times 4 = 16 \\ \\ \\ \\ 2. \: 14 \div \frac{5}{6} \\ \\ = \geqslant 14 \times \frac{6}{5} \\ \\ = \geqslant \frac{84}{5} = 16.8 \\ \\ \\ 3. \: \: \: 3 \div 2 \frac{1}{3} \\ \\ = \geqslant 3 \div \frac{7}{3} \\ \\ = \geqslant 3 \times \frac{3}{7} \\ \\ = \geqslant \frac{9}{7} \\ \\ \\ 4. \: \: \: 5 \: \div \: 3 \frac{4}{7} \\ \\ = \geqslant 5 \div \frac{25}{7} \\ \\ = \geqslant 5 \times \frac{7}{25} \\ \\ = \geqslant \frac{7}{5}$
