$\frac{1 \cdot 10^{- 15}}{4.2 \cdot 10^{- 7}}$

Step 1

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

$0$

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.

$2.\overline{380952} \times 10^{- 9}$
