Fill in the blanks: 10 times 160 equals blank times 100, which equals blank.

Let’s start with the first blank. To fill out the first blank, we need to break 160 into different parts. 160 equals 10 times 16. And if we bring down our 10, we see that 10 times 10 times 16 is the same thing as saying 10 times 160.

And what if we multiply 10 times 10? We know that 10 times 10 equals 100. And then, we bring down our times 16. 10 times 160 is the same thing as saying 100 times 16. And that means we can put 16 in our first box. 10 times 160 equals 16 times 100.

And to find the answer to our final box, we need to multiply 16 by 100. 16 times 100 equals 16 hundreds. And that’s a one and a six with two zeros behind it, a 16 with two zeros.

10 times 160 equals 16 times 100, which equals 1600.
