Math Problem of the Week - Upper Elementary - Apr. 24, 2022 to Apr. 30, 2022

Upper Elementary: 

Question: Spot the dog likes to bury bones in the backyard. On Friday, he buried half of his bones. On Saturday, he dug up ³/₄ of the bones he buried the day before. If spot started with 72 bones on Friday, then how many bones did he dig up on Saturday?

Answer:  27 bones

Solution: Spot buried half of 72 = 36 bones on Friday. To find out how many bones he dug up on Saturday, first we need to find 1 quarter of 36 by finding half of a half of 36. That's half of 18, which is 9. Since Spot dug up 3 quarters of the bones he buried, we know that he dug up 9 x 3 = 27 bones on Saturday.
