Question

Which number sentence shows the correct placement of the decimal point in the product, based on the two factors?

3.48 × 42.37 = 147.4476
0.39 × 7.2 = 28.08
43.72 × 9.2 = 4,022.24
23.2 × 8.8 = 20.416

Answer 1

3.48 x 42.37 = 147.4476, is the number sentence that shows correct placement of the decimal point in the product.

This is because, we can see that the first factor has two spaces going for the right to the decimal. Same with the second factor as well. Then, we just have to add the spaces from the right to the decimal, giving us 4 decimal spaces. Knowing this information, we have to move four spaces going from the right to the left, making this sentence true.
