### Example Question #582 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

Stacy has started collecting coins.  She has twice as many wheat pennies as she does dimes, and three times as many quarters as she does dimes.  If Stacy has  dimes, what is the ratio of wheat pennies to quarters?      Explanation:

We also know that she has twice as many wheat pennies, so we must multiply by to find the total number of wheat pennies. We also know that Stacy has three times as many 1986 quarters, so we multiply by to find the total number of 1986 quarters. Now our ratio of wheat pennies to 1986 quarters is , but this can be simplified because both numbers are divisible by .  So our ratio becomes 2 Next →
