$\frac{5.4 \cdot 10^{2} \cdot 7000}{1.8 \cdot 10^{8}}$

Step 1

Convert the fraction to a decimal by dividing the numerator by the denominator.

$0.021$

Step 2

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the $10$ . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

$2.1 \times 10^{- 2}$
