Problem solving by Junefia, Janett and Marilyn

  1. There are 20 people on the bus.  A ¼ are children.  How many children are there?

There are 5 children on the bus.

¼ of 20= 5

5 X 4=20



2. There were 300 apples on the tree.   Janett eats ½ of them.  How many does she eat?

She ate 150 of the apples. 

½ of 300= 150

150 X 2= 300



3. Mama has $5. She buys a nut bar for $1.10.

How much change does she get?

She gets $3.90 change. $5.00 - $1.10= $3.90.

Azalea has $10. She gets $4.60 change after buying a packet of rice biscuits.

How much do the biscuits cost?

The biscuits cost $5.40. $10.00 - $4.60= $5.40

Selu pays for $1.10 for two apples. She gets 90 cents change.

How much money did she give to the person at the checkout?

She gave $2.00 to the person at the checkout. $1.10 + 90 cents= $2.00 


On Monday, Moana, Junefia, and Langiola shared some lollies they'd been given.

Junefia got half as many lollies as Moana, and Langiola got a third as many lollies as Moana got.

They got the same number of lollies each day up to Friday.

If Moana got 18 lollies on Wednesday, how many lollies did Junefia get on Thursday?

How many lollies did Langiola get that week?
