Chapter 1, Problem 113

Multiply or divide as indicated. 32.48 ÷ 11.6

Verified step by step guidance
1
Identify the operation: The problem asks to divide 32.48 by 11.6, so we will perform the division \( \frac{32.48}{11.6} \).
To simplify the division of decimals, multiply both the numerator and the denominator by 10 to eliminate the decimal in the denominator. This gives \( \frac{32.48 \times 10}{11.6 \times 10} = \frac{324.8}{116} \).
Now, perform the division \( \frac{324.8}{116} \) by dividing 324.8 by 116 using long division or a calculator.
Express the quotient as a decimal number, which will be the result of the division.
If needed, simplify the decimal or convert it to a fraction for the final answer.
