Treat 4 as 4/1. When multiplying fractions multiply both top and bottom: $\displaystyle \frac{a}{c} \cdot \frac{b}{d} = \frac{ab}{cd}$

Also do you mean $\displaystyle 4+\frac{4}{21} or 4 \times \frac{4}{21}$ in the first term? I will guess the former

$\displaystyle

4(4+\frac{4}{21}) = 16 + \frac{16}{21} = \frac{16 \cdot 21 + 16}{21} = \frac{352}{21}$ - Dec 8th 2009, 06:59 AMandyboy179
