Answer 1

$= \bigg[ 4\dfrac{1}{5} \div \bigg( 1\dfrac{3}{4} - \dfrac{1}{2} ( \ \ 3 \dfrac{1}{2} - \dfrac{1}{4} - \dfrac{1}{6} \ \ ) \bigg) \bigg]$

$= \bigg[ 4\dfrac{1}{5} \div \bigg( 1\dfrac{3}{4} - \dfrac{1}{2} ( \ \ 3 \dfrac{6}{12} - \dfrac{3}{12} - \dfrac{2}{12} \ \ ) \bigg) \bigg]$

$= \bigg[ 4\dfrac{1}{5} \div \bigg( 1\dfrac{3}{4} - \dfrac{1}{2} ( \ \ 3 \dfrac{1}{12} \ \ ) \bigg) \bigg]$

$= \bigg[ 4\dfrac{1}{5} \div \bigg( 1\dfrac{3}{4} - \dfrac{1}{2} ( \ \ \dfrac{37}{12} \ \ ) \bigg) \bigg]$

$= \bigg[ 4\dfrac{1}{5} \div \bigg( 1\dfrac{3}{4} - \dfrac{37}{24} \bigg) \bigg]$

$= \bigg[ 4\dfrac{1}{5} \div \bigg( 1\dfrac{18}{24} - 1\dfrac{13}{24} \bigg) \bigg]$

$= \bigg[ 4\dfrac{1}{5} \div \dfrac{5}{24} \bigg]$

$= \bigg[ \dfrac{21}{5} \div \dfrac{5}{24} \bigg]$

$= \bigg[ \dfrac{21}{5} \times \dfrac{24}{5} \bigg]$

$= \dfrac{504}{25}$

$= 20 \dfrac{4}{25}$

.
