Rocco has 15 cups of flour in his storage unit. He needs 2/8 that amount to use for his homemade volcano. What is the total number of cups needed for his experiment?
There are three different states a volcano can be in: active, dormant, or extinct. To be active it must have erupted in the last two thousand years; to be dormant means it has not erupted recently but has the potential to again; and to be extinct means it probably won’t erupt again.
