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