Question

mrs. mcglashan is making paint for her class. she needs 3/4 cup of warm water for each batch. mrs. mcglashan has a 1 cup measure that has no markings can she make 8 batches of paint using only the 1 cup measuring cup? describe two ways you can find the answer.

Answer 1

One way to find the answer is by dividing 8 batches by 3/4 to see if the quotient will end up being a whole number.

When you solve 8 / 3/4, you will get 10 2/3.  Because this is a rational number, and not an integer, it is not possible for her to make 8 batches of paint without measurements on the cup.
