Question

Leanne multiplied 8*4.3 and got 32.24.is Leanne correct? Use an area model to explain your answer.

Answer 1

No, Leanne is not correct.

To multiply 8 and 4.3, we multiply the whole numbers and then multiply the decimals.

8 * 4 = 32

0.3 * 8 = 2.4

Adding these two products together, we get:

32 + 2.4 = 34.4

Therefore, the correct answer to 8 * 4.3 is 34.4, not 32.24.
