To find half of 1 3/4, we first need to convert the mixed number into an improper fraction. Since 1 3/4 means 1 whole and 3/4 of another whole, we can convert it as follows:
1 3/4 = (1 × 4 + 3)/4 = (4 + 3)/4 = 7/4.
Now, to find half of 7/4, we multiply it by 1/2:
(1/2) × (7/4) = 7/8.
Thus, half of 1 3/4 is 7/8.
