Jeremy incorrectly says that 7 (1 / 8) is the same as 7.18. Convert 7 (1 / 8) to a decimal correctly, then explain Jeremy's likely error. A. 7 (1 / 8) = 7.125; Jeremy likely misinterpreted the fraction as a decimal. B. 7 (1 / 8) = 7.18; Jeremy likely made a rounding error. C. 7 (1 / 8) = 7.875; Jeremy likely misread the fraction. D. 7 (1 / 8) = 7.081; Jeremy likely used the wrong conversion.

Step 1:
Let's solve this step by step:

Step 2:
: Convert 7 (1 / 8) to a decimal

• $$\frac{1}{8} = 0.125
• To convert a mixed number to a decimal, first convert the fraction • Add this to the whole number 7

Step 3:
: Perform the decimal addition

7 + 0.125 = 7.125

Step 4:
: Verify the calculation

• $$7 (1/8) = 7.125
• This matches option A exactly

Step 5:
: Analyze Jeremy's likely error

• Jeremy said 7.18, which is close to but not the same as 7.125 • This suggests he likely misinterpreted the fraction as a decimal • Specifically, he may have incorrectly read 1 / 8 as 0.18 instead of 0.125

Final Answer

Key Insights: - Mixed numbers convert by adding the whole number to the decimal equivalent of the fraction - \frac{1}{8} = 0.125 - Always carefully convert fractions to their precise decimal representation
