Walt and Amy each have the same number of pennies. Walt made equal stacks of 10 pennies with none left over. Amy made equal stacks of 8 pennies with none left over. What is the least number of pennies that each person could have? Explain how you found your answer. Thanks!
The least number of pennies that each person could have is 40. This is because 40 is divisible by both 8 and 10 (40/8=5 , 40/10=4).
