$\frac{7 \cdot 10^{9}}{4 \cdot 10^{2}}$

Step 1

Group coefficients together and exponents together to divide numbers in scientific notation.

$(\frac{7}{4}) (\frac{10^{9}}{10^{2}})$

Step 2

Divide $7$ by $4$ .

$1.75 \frac{10^{9}}{10^{2}}$

Step 3

Subtract the exponent from the denominator from the exponent of the numerator for the same base

$1.75 \cdot 10^{9 + 2 \cdot - 1}$

Step 4

Multiply $2$ by $- 1$ .

$1.75 \cdot 10^{9 - 2}$

Step 5

Subtract $2$ from $9$ .

$1.75 \cdot 10^{7}$
