$\frac{4.5 \cdot 10^{- 3} \cdot 2 \cdot 10^{4}}{3.6 \cdot 10^{5} \cdot 2.5 \cdot 10^{- 2}}$

Step 1

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

$0.01$

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.

$1 \times 10^{- 2}$
