Answer:
7/8 - 1/2 = \frac{3}{8}
Step-by-Step Solution
Step 1
Identify the Fractions
To subtract fractions, they must have the same denominator (bottom number).
\frac{7}{8} - \frac{1}{2} = ?
Step 2
Find the Common Denominator
The denominators are different (8 and 2), so we need a common denominator.
The Least Common Denominator (LCD) of 8 and 2 is 8.
\text{LCD}(8, 2) = 8
Step 3
Convert First Fraction
Multiply top and bottom by 1
\frac{7}{8} = \frac{7 \times 1}{8 \times 1} = \frac{7}{8}
Step 4
Convert Second Fraction
Multiply top and bottom by 4
\frac{1}{2} = \frac{1 \times 4}{2 \times 4} = \frac{4}{8}
Step 5
Subtract the Fractions
Now both fractions have the same denominator.
\frac{7}{8} - \frac{4}{8} = \frac{7 - 4}{8} = \frac{3}{8}
Step 6
Final Answer
The result is 3/8
As a decimal: 0.375
\frac{7}{8} - \frac{1}{2} = \frac{3}{8}
