Step-by-step Solution
To find out how much chocolate is left at the end of the evening, we need to subtract the amount of chocolate eaten from the initial amount of chocolate bars left.
Given:
- Initial amount of chocolate bars left: 4 and one-eighth (4 + 1/8)
- Amount of chocolate bars eaten: 3 and three-quarters (3 + 3/4)
Let's calculate the amount of chocolate left at the end of the evening.
Calculate the value by following steps:
- step0: Calculate:
\(4+\frac{1}{8}-\left(3+\frac{3}{4}\right)\)
- step1: Add the terms:
\(4+\frac{1}{8}-\frac{15}{4}\)
- step2: Reduce fractions to a common denominator:
\(\frac{4\times 8}{8}+\frac{1}{8}-\frac{15\times 2}{4\times 2}\)
- step3: Calculate:
\(\frac{32}{8}+\frac{1}{8}-\frac{30}{8}\)
- step4: Transform the expression:
\(\frac{32+1-30}{8}\)
- step5: Calculate:
\(\frac{3}{8}\)
The amount of chocolate left at the end of the evening is \( \frac{3}{8} \) or 0.375 chocolate bars.
Quick Answer
The amount of chocolate left is 0.375 chocolate bars.
