## Basic College Mathematics (10th Edition)

4.7$\div$9.3 = $\frac{47}{10}\div\frac{93}{10}$ (writing decimals as fractions) = $\frac{47}{10}\times\frac{10}{93}$ (division of fractions is multiplication by the reciprocal of the second fraction) = $\frac{47}{93}$ = 0.5053 to round to the nearest hundredth. We keep 0.50 and look the thousandths place which is 5 so need to add 1 to the hundredths place. i.e. 0.50+0.01 = 0.51 (rounded)
