URGENT!

Answer 1

$3.(2) \div 0.(2)$

$= \frac{32 - 3}{9} \div \frac{2}{9}$

$= \frac{29}{9} \times \frac{9}{2}$

$= \frac{29}{2}$

$10.2(46) \div 1.2(4)$

$= \frac{10246 - 102}{990} \div \frac{124 - 12}{90}$

$= \frac{10144}{990} \div \frac{112}{90}$

$= \frac{10144}{990} \times \frac{90}{112}$

$= \frac{5072}{11} \times \frac{1}{56}$

$= \frac{2536}{11} \times \frac{1}{28}$

$= \frac{1268}{11} \times \frac{1}{14}$

$= \frac{634}{11} \times \frac{1}{7}$

$= \frac{634 \times 1}{11 \times 7}$

$= \frac{634}{77}$
