D. $$\frac {3.2}{50}$$

A
4.6
4.6

## Solution

We have: options (a) $$\frac {32}{0.05}=\frac{3200}{5}=640$$
(b) $$\frac {0.320}{50}=\frac{0.03200}{5}=0.00640$$
(c) $$\frac {3.2}{0.05}=\frac{320}{5}=64$$
(a) $$\frac {3.2}{50}=\frac{0.3200}{5}=0.0640$$
Among options (a),(b),(c) and (d) we see that option (a) has the largest value.
