 $3.6×4.5 = $ $0.48 + 3.72 = $ $3.7 - 2.7÷3 = $
$21.9÷0.03 = $ $2.55÷1.5 = $ $48÷12×2.5 = $
$3.88 + 6.12 = $ $200×80\% = $ $\frac{1}{5}÷2÷\frac{1}{5} = $
$\frac{9}{4}×\frac{4}{21} = $ $\frac{4}{5}-\frac{3}{4} = $ $(\frac{1}{3}+\frac{4}{5})×30 = $
$\frac{5}{8}×\frac{3}{65} = $ $\frac{7}{11}÷\frac{21}{22} = $ $7.5×9 + 7.5 = $
$\frac{3}{2}÷\frac{3}{8} = $ $\frac{5}{12}-\frac{1}{12} = $ $(0.18 + 0.9)÷9 = $
$8.6×5 = $ $\frac{3}{5}+0.1 = $ $3.7 + 2.61 + 6.3 = $
$\frac{5}{6}÷\frac{2}{5} = $ $\frac{1}{3}÷30\% = $ $18÷\frac{3}{5}×\frac{1}{3} = $
$1 - 15\% = $ $2100÷400 = $ $1÷\frac{1}{3}+\frac{1}{3}÷1 = $
$3.2 - 1.05 = $ $\frac{8}{5}×37.5\% = $ $1.2×\frac{2}{5}+\frac{2}{5}×1.3 = $
