A recipe calls for 1 1/3 cups of flour. Harold has 1/2 cup of flour. How much more flour does Harold need to make the recipe?
1 1/3 = 4/3 = 8/6
1/2 = 3/6
8/6 - 3/6 = 5/6
To find out how much more flour Harold needs to make the recipe, we need to subtract the amount of flour he has from the amount required by the recipe.
The recipe calls for 1 1/3 cups of flour, which can also be written as 4/3 cups of flour. Harold has 1/2 cup of flour.
To subtract fractions, we need a common denominator. In this case, the least common denominator is 6.
1/2 cup of flour can be written as 3/6 cups.
Now we can subtract:
4/3 - 3/6
To subtract fractions with the same denominator, we subtract the numerators and keep the denominator the same:
4/3 - 3/6 = (4 - 3)/3 = 1/3
So Harold needs 1/3 cup more flour to make the recipe.
