Fractions and Model

A construction company is digging a pit to build the foundation of a house.
At the end of the first day, the company had hauled away 1/6 of a truckload of dirt.
On the second day, they hauled away 2/6 of a truckload. How many truckloads did they haul away in all?

• 1/4 truckload

• 1/2 truckload

• 3/4 truckload

• 1/3 truckload

3/5 + 1/4 = 

• 5/20

• 12/20

• 7/20

• 17/20

Add these fractions.
1/2 + 1/3 =

• 5/6

• 2/5

• 1/5

• 1

1/2 x 3

• 3/2

• 2/2

• 1/2

• 3/1

1/7 x 2

• 1/7

• 1/2

• 7/2

• 2/7

What multiplication equation is show here?

• 1/2 x 3 = 3/2 

• 3/2 x 2 = 6/2 = 2

• 1/4 x 5 = 5/4 = 1 1/4

• 1/4 x 4 = 4/4 = 1

• Yes, you will get the same answer.

• No, you will get a different answer.
