1 and 3/4 as an improper fraction

7/4 you do this because, for example you can think of it like pizza and pizza slices. You have 1 pizza and 3/4 of a pizza, let’s say each slice is 1/4 of a pizza. How many slices do you have altogether? Seven. You can also think of 1 as 4/4, so the just add 3/4 + 4/4 (which is technically just 3+4) = 7/4

It’s 7/4 because you multiply the whole number and the denominator together and add the product to the numerator. So 1 * 4 = 4 + 3 = 7/4.
