How many 1/3 cups do you need to make 1/2 cup?
one and a half
We need to figure out how much more than
if we subtract
In order to subtract or add fractions we need to make the denominators (the bottom parts) of both fractions equal to each other. In order to do that we find the Least Common Multiple between them. In this case between 2 and 3. It is 6, which is 2 times 3. Now we multiply the bottom and top of each fraction by the number in that multiplication above that is missing to get to 6, like this:
Notice that we multiply the
Once we make those multiplications we get:
We can see from the previous calculations that
