4th Grade Math
posted by Anonymous .
The chickens on a farm eat 3 times as much grain as the turkeys do per week. The chickens and turkeys eat a total of 52 pounds of grain every week. How much grain do the chickens and turkeys each eat every week?
Any help would be appreciated, thank you in advance!
Let t = the amount the turkeys eat.
t + 3t = 52
4t = 52
t = 13 pounds
so easy with a bit of algebra, but algebra in grade 4 ?
suppose we put the grain in 4 buckets
(if we give 3 buckets to the chickens and 1 bucket to the turkeys, we do what it says)
then wouldn't each bucket contain 13 pounds ?
so the chickens get 3x13 or 39 pounds
the turkeys get 13 pounds
