Leanne multiplied 8 x 4.3 and got 32.24. Is Leanne correct?Use an area model to explain your answer
dlinn [17]

Answer:

No, not correct.  

Step-by-step explanation:

Note that 8 * 4.3 can be broken up as follows:

8 * (4 + 0.3)

and that 4*8 =32, and that 0.3(8) = 2.4 (not 0.24).

Then 8 * (4 + 0.3) becomes 32 + 2.4 = 34.4
