Question

30 cm³ milk is divided among some children equally. Each child took 4½ cm³ milk. how many children took milk
​

Answer 1

$\frac{30}{4 \frac{1}{2} } =$

$\frac{30}{ \frac{4 \times 2 + 1}{2} } =$

$\frac{30}{ \frac{9}{2} } =$

$30 \div \frac{9}{2} =$

$30 \times \frac{2}{9} =$

$\frac{60}{9} =$

$\frac{3 \times 20}{3 \times 3} =$

$\frac{20}{3} =$

$6.666$

Which is unacceptable so we can say at least 6 children got 4½ cm³ milk.
