To subtract \( 7 \frac{1}{4} \) from \( 8 \), you can first convert \( 8 \) into a fraction:
\[ 8 = \frac{8}{1} \]
Next, to perform the subtraction, you need to express \( 7 \frac{1}{4} \) as an improper fraction:
\[ 7 \frac{1}{4} = 7 + \frac{1}{4} = \frac{28}{4} + \frac{1}{4} = \frac{29}{4} \]
Now, subtract \( \frac{29}{4} \) from \( 8 \):
First, convert \( 8 \) into a fraction with a denominator of \( 4 \):
\[ 8 = \frac{32}{4} \]
Now perform the subtraction:
\[ \frac{32}{4} - \frac{29}{4} = \frac{32 - 29}{4} = \frac{3}{4} \]
Therefore,
\[ 8 - 7 \frac{1}{4} = \frac{3}{4} \]
