A meatloaf recipe calls for #7/8# cup of breadcrumbs for the loaf and the topping. If #3/4# is used for the loaf, what fraction of a cup used for the topping?
To find what fraction is used for the topping, we need to subtract the fraction used for the loaf from the total amount of breadcrumbs:
We know two of those values, which we can plug in:
In order to subtract fractions, we need a common denomator. Here, we can multiply the blue fraction by
Now we can subtract the fractions:
