Sharing Them Equally?
Here are six bananas.
Here are three monkeys.
If they share the bananas equally, each monkey will get 2 bananas.
6 bananas divided into 3 equal parts = 2 bananas each 6 + 3 = 2
If there are six bananas and two monkeys,
Each monkey will get three bananas.
Six bananas + 2 = 3 bananas each.
6 ÷2 = 3
1.If there are 60 bananas and two monkeys, how many will each monkey get?
Ans. 60 ÷ 2 = 30 bananas
