8 - 7 1/4 can be written as 8 - 7 4/4.
To subtract, we need to have a common denominator. The common denominator for 1/4 and 4/4 is 4, so we can rewrite the expression as:
8 - 7 4/4 = 8 - 28/4 + 7/4
Next, we subtract the whole numbers:
8 - 28/4 + 7/4 = 1 - 28/4 + 7/4
Now, we can subtract the fractions:
1 - 28/4 + 7/4 = 1 - (28 + 7)/4
Simplifying further:
1 - (28 + 7)/4 = 1 - 35/4
To subtract fractions, we need a common denominator. The common denominator for 1 and 35/4 is 4, so we can rewrite the expression as:
1 - 35/4 = 4/4 - 35/4
Now, we can subtract the fractions:
4/4 - 35/4 = (4 - 35)/4
Simplifying the numerator:
(4 - 35)/4 = -31/4
Therefore, 8 - 7 1/4 is equal to -31/4.
