of each square represent?
b. What area is represented
by each square?
c. What is 0.3 x 0.5? Show
your reasoning.

Answer 1

Explanation:

represent the product of two decimals. We have .3 times .5. In my diagram, each square is going to Have a side length of .1. It's hard to read, so I'll just label one of them. That means the area represented by each square is .1 times .1 1/10 times 1/10 which is 100. Mhm. And then we can determined from the diagram that we have 123456789, 10, 11, 12, 13, 14, 15 of those hundreds. That is our product. Let's find this product a different way. Just to confirm, .3 is 3/10 .5 is 5/10, three times 5 is 15, 10 times 10 is 100. and once again We have calculated the product to be 15 hundreds. I hoped that helped
