Question

Describe how the product of 0.4 × 2 would look on a ten-square grid.

The product would have _____
squares shaded out of 10.

Answer 1

Well, let's start with the first part of the question. What is 0.4 x 2?

Answer 2

0.8

Answer 3

That's right. Now in this case, we're going to say that each square equals 0.1. So how many squares would be shaded

Answer 4

2.8?

Answer 5

or 2.4

Answer 6

Well there would be 8/10 squares shaded. Another way to look at is is 8 divided by 10 would equal 0.8

Answer 7

so 0.8 is the answer ?

Answer 8

Just 8. If you were to shade 0.8 squares, you would have a product of 0.08 shown, but if you shade 8 squares, you would have a product of 0.8 shown. So the number of squares shaded divided by the total number of squares (in this case 10) will give you the product that the shaded squares represent.

Does that make sense?

Answer 9

yes
