Eight less than nine is one, and eight less than ten is two. Therefore, the numbers that are eight less than nine and ten are one and two, respectively.
x - 10 is the equation you would use to find the answer. Since you don't have a specific number to subtract from, you have to use x, and "ten less than" means that you have to subtract from your first number.

Expressed algebraically, this is equal to 3x - 10.
5 ten thousandths in decimal form is 0.0005 Any decimal number that has three zeros after the decimal point and then a lower number than 5 is smaller. If the number has more than three zeros after the decimal point it is smaller.
