“We must stop eating!' cried Toad as he ate another.”
―Arnold Lobel, Frog and Toad Together
Frog and Toad are friends, and sharing is what friends do, so of course Frog and Toad will share the food they find around their pond! Help Frog and Toad figure out how many flies to eat, and how many to leave flying around. Practice your addition, subtraction, fractions, and other elementary school math skills in this week’s word problem challenge.
Question: A frog eats half of the flies around a pond. A toad eats a third of the remaining flies. What fractional part of the flies are left at the pond?
Do your best! When you're ready, check below for the solution.
Solution: After the frog eats half of the flies, the other half of the flies are left. The toad therefore eats a third of a half of the flies, and a third of a half is a sixth. Since 1/2 + 1/6 = 2/3, that means 1/3 of the flies are left at the pond.
