### Question

Simplify and express in standard form $$\frac{0.00275 \times 0.0064}{0.025 \times 0.08}$$

A) 8.8 x 10-1

B) 8.8 x 10-2

C) 8.8 x 10-3

D) 8.8 x 103

### Explanation:

$$\frac{0.00275 \times 0.0064}{0.025 \times 0.08}$$
Removing the decimals = $$\frac{275 \times 64}{2500 \times 800}$$
= $$\frac{88}{10^4}$$
88 x 10-4 = 88 x 10-1 x 10-4
= 8.8 x 10-3
