1 7/8-1/4

To subtract \( \frac{1}{4} \) from \( 1 \frac{7}{8} \), first convert the mixed number into an improper fraction.

1. Convert \( 1 \frac{7}{8} \): \[ 1 \frac{7}{8} = \frac{(1 \times 8) + 7}{8} = \frac{8 + 7}{8} = \frac{15}{8} \]

2. Now, we need to subtract \( \frac{1}{4} \) from \( \frac{15}{8} \). First, we need a common denominator. The least common denominator of 8 and 4 is 8.

3. Convert \( \frac{1}{4} \) to have a denominator of 8: \[ \frac{1}{4} = \frac{1 \times 2}{4 \times 2} = \frac{2}{8} \]

4. Now, perform the subtraction: \[ \frac{15}{8} - \frac{2}{8} = \frac{15 - 2}{8} = \frac{13}{8} \]

5. Convert \( \frac{13}{8} \) back to a mixed number: \[ \frac{13}{8} = 1 \frac{5}{8} \]

So, \( 1 \frac{7}{8} - \frac{1}{4} = 1 \frac{5}{8} \).
