Question

What is the product of 43 and 2.4 (24 tenths)? Imagine it in an area model where you separate 43 into 40 and 3.

a) 103.2
b) 10.32
c) 432
d) 4320

Answer 1

The product of 43 and 2.4 is found by multiplying each part (40 and 3) by 2.4 and then adding the results together, giving us 103.2.

Step-by-step explanation:

The product of 43 and 2.4 (24 tenths) could be found by using an area model, where 43 is separated into 40 and 3. We multiply each part by 2.4 and then add the results:

• 40 × 2.4 = 96
• 3 × 2.4 = 7.2

Adding these together gives us:

96 + 7.2 = 103.2.

So the product of 43 and 2.4 is 103.2, which means the correct answer is (a) 103.2.
