Rounding

Rounding is used to simplify numbers. When rounding we are creating numbers that are

approximate to their original value. The benefit to rounding is that it gives us numbers

that are easier to work with. The downside to rounding is that the numbers will not

always be exact.

Example 1:

We use rounding in our everyday lives. For example, you are hosting a party and are

expecting eighteen (18) guests. You would like to purchase party favors for your guests

but they only come in packages of ten (10). How many packages should you purchase?

1 2 3 4 5 6 7

8 9 10

1 2 3 4 5 6 7

8 9 10

18 – 10 = 8

11 12 13 14 15 16 17 18

One package would leave 8 party-goers

Two packages would give you enough to

without any party favors.

cover 18 guests with 2 left over.
