When multiplied by 8, the result is a whole number.

In order for a decimal to be a whole number, there has to be a zero in the decimal.

We need to create a zero by multiplying 8x5 to create 40. We can start with 8 x 0.5, 8x 0.25, or 8 x0.125.

Question number 2

What code numbers fit these clues?

8,640.125

8,604.125

8622.125

8613.125

8631.125

We knew that 300 numbers were in between 8,500 and 8,800. We had to find numbers or decimal numbers that when multiplied, the product was a whole number. Then we took 8 and found that 3/4 of it was 6. Since the total number had to equal 26 and the digit in the hundredths place is 2 times the digit in the tenths place, so the decimal place is 0.125. After we found most of the numbers and added them. The sum was 22. Then we subtracted 26 from 22 to get 4. So then we knew that the tens and ones place had to equal 4 when added. We found 5 answers: 8,640.125; 8,604.125; 8,613.125; 8,631.125; 8,622.125.
