\]
Write your answer in simplest form.
Solution
Solution Steps
To solve the given expression, we need to perform the following steps:
Multiply the two fractions \(\frac{1}{3}\) and \(\frac{7}{8}\).
Subtract the fraction \(\frac{1}{4}\) from the result obtained in step 1.
Simplify the resulting fraction to its simplest form.
Step 1: Multiply the Fractions
We start by multiplying the fractions \(\frac{1}{3}\) and \(\frac{7}{8}\):
\[
\frac{1}{3} \cdot \frac{7}{8} = \frac{1 \cdot 7}{3 \cdot 8} = \frac{7}{24}
\]
Step 2: Subtract the Fraction
Next, we subtract \(\frac{1}{4}\) from the result obtained in Step 1:
\[
\frac{7}{24} - \frac{1}{4}
\]
To perform this subtraction, we need a common denominator. The least common multiple of 24 and 4 is 24. We convert \(\frac{1}{4}\) to have a denominator of 24:
\[
\frac{1}{4} = \frac{1 \cdot 6}{4 \cdot 6} = \frac{6}{24}
\]
Now we can subtract:
\[
\frac{7}{24} - \frac{6}{24} = \frac{7 - 6}{24} = \frac{1}{24}
\]
Step 3: Simplify the Result
The result \(\frac{1}{24}\) is already in its simplest form.
