Step 3.1.1

Factor $1$ out of $- 7 \cdot 10^{- 8}$ .

$\frac{1 \cdot - 7 \cdot 10^{- 8}}{25} \div c \cdot 29$

Step 3.1.2

Rewrite $25$ as $1 (25)$ .

$\frac{1 \cdot - 7 \cdot 10^{- 8}}{1 (25)} \div c \cdot 29$

Step 3.1.3

Cancel the common factor.

$\frac{1 \cdot - 7 \cdot 10^{- 8}}{1 \cdot 25} \div c \cdot 29$

Step 3.1.4

Rewrite the expression.

$\frac{- 7 \cdot 10^{- 8}}{25} \div c \cdot 29$

Step 3.2.1

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

$(\frac{- 7}{25}) (\frac{10^{- 8}}{1}) \div c \cdot 29$

Step 3.2.2

Divide $- 7$ by $25$ .

$- 0.28 \frac{10^{- 8}}{1} \div c \cdot 29$

Step 3.2.3

Divide $10^{- 8}$ by $1$ .

$- 0.28 \cdot 10^{- 8} \div c \cdot 29$

Step 3.3

Move the decimal point in $- 0.28$ to the right by $1$ place and decrease the power of $10^{- 8}$ by $1$ .

$- 2.8 \cdot 10^{- 9} \div c \cdot 29$

Step 3.4

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$- 2.8 \cdot \frac{1}{10^{9}} \div c \cdot 29$

Step 3.5

Raise $10$ to the power of $9$ .

$- 2.8 \cdot \frac{1}{1000000000} \div c \cdot 29$

Step 4

Combine $- 2.8$ and $\frac{1}{1000000000}$ .

$\frac{- 2.8}{1000000000} \div c \cdot 29$

Step 5

Divide $- 2.8$ by $1000000000$ .

$0 \div c \cdot 29$

Step 6

Rewrite the division as a fraction.

$\frac{0}{c} \cdot 29$

Step 7

Move the negative in front of the fraction.

$- \frac{0}{c} \cdot 29$

Step 8
