Answer
45
Work Step by Step
25.2$\div$0.56
= $\frac{252}{10}\div\frac{56}{100}$ (writing decimals as fractions)
= $\frac{252}{10}\times\frac{100}{56}$ (division of fractions is multiplication by the reciprocal of the second fraction)
= $\frac{28\times9}{1}\times\frac{10}{28\times2}$
= $\frac{90}{2}$
= 45
