$0.28÷0.07 = $ $3.14 - 0.75 = $ $\frac{3}{5}÷\frac{7}{5} = $
$\frac{7}{9}-\frac{1}{6} = $ $\frac{3}{16}×\frac{4}{9} = $ $\frac{5}{7}+\frac{3}{20} = $
$720÷60 = $ $700 - 296 = $ $1.3 - 1.17 = $
$8.1÷1.5 = $ $\frac{4}{5}+\frac{5}{12} = $ $0.85÷1.7 = $
$25÷100 = $ $3.7×20\% = $ $0.25×300 = $
$\frac{4}{5}÷\frac{3}{2} = $ $\frac{7}{8}-\frac{5}{6} = $ $2.63 + 3.7 = $
$8.1÷0.09 = $ $3\frac{1}{3}-\frac{1}{4} = $ $0.24×0.15 = $
