Answer 1

$1)1.6 \div \frac{2}{3} = 1.6 \times \frac{3}{2} = \frac{4.8}{2} = 2.4$
$2)1 \frac{1}{7} \times 1.4 = \frac{8}{7} \times 1.4 = \frac{8 \times 1.4}{7} = \frac{11.2}{7} = 1.6$
$3)2.4 \times 1.6 = 4$
$4)3.84 \div 0.08 = 50$
$5)9 \div 4 \frac{2}{7} = 9 \div \frac{30}{7} = 9 \times \frac{7}{30} = \frac{63}{30} = \frac{21}{10} = 2.1$
$6)9 - 2.1 = 6.9$
$7)2.25 - 1 \frac{1}{4} = 2.25 - \frac{5}{4} = 2.25 - 1.25 = 1$
$8)6.9 \div 0.23 = 30$
$9)30 \times 1 = 30$
$10)50 - 30 = 20$
