Judy is using a recipe to make a special cake for Mrs. Minter’s birthday. She uses 2/8 cups of brown sugar, 1/8 cup of white sugar and 5/8 cup of dyed (colored) sugar (to make the cake red). Is Judy going to use more than, less than, or exactly 1 cup of sugar altogether? How do you know?
What is exactly 1 cup. Add 2/8, 1/8, 5/8. Get 8/8 = 1 cup.
