The numbers are 15, 9, and 3.
The product. Of three negative numbers is negative I hope you can get 100 in your homework
It means write down three pairs of numbers that are relatively prime like 4 and 9, 5 and 6, 13 and 25
The product of three positive numbers is positive. The product of three negative numbers is negative.
The product of three negative numbers is negative.
You take the two numbers that you need which is the width and the height then you multiply the width and height and multiply the two numbers to find the product and that's your answer! :)
If all three numbers are positive then the product obviously has to be positive. If TWO of the three numbers are negative, then the product is also positive. But if exactly ONE of the three numbers is negative or if all THREE are negative, then the product must be negative. In general, a product of numbers is negative if an ODD NUMBER of the terms is negative.
