What is 4-1 1/4 + 1/2?

Answer 1

First, let's convert the mixed number 1 1/4 to an improper fraction:
1 1/4 = (4/4) + (1/4) = 5/4

Now we can solve the expression:
4 - (5/4) + (1/2)

To add or subtract fractions, we need to find a common denominator. In this case, the common denominator is 4:
4 = (16/4)
(5/4) = (5/4)
(1/2) = (2/4)

Now we can rewrite the expression with the common denominator:
(16/4) - (5/4) + (2/4)

Next, we can combine the numerators:
16 - 5 + 2 = 13

Now we have:
13/4

Therefore, 4 - 1 1/4 + 1/2 is equal to 13/4.
