Question

Use the decimals 3.43, 8.93, and 5.5 to write two different addition facts and two different subtraction facts.

Answer 1

We have that a number fact is an equation made up of three different numbers.

We can say that:

Addition facts:

3.43 + 5.5 = 8.93

And also that:

5.5 + 3.43 = 8.93

(In this case, we have the commutative property of the addition).

Subtraction facts:

8.93 - 3.43 = 5.5

8.93 - 5.5 = 3.43
