Set up algebraically.
X/10 = 4
multiply through by 10
X = 40
8/10 You can divide the top and bottom by the same number. In this case, divide both 8 and 10 by 2: 4/5
A meter has 10 decimeters, so just divide the number of decimeters by 10.A meter has 10 decimeters, so just divide the number of decimeters by 10.A meter has 10 decimeters, so just divide the number of decimeters by 10.A meter has 10 decimeters, so just divide the number of decimeters by 10.

We multiply or divide the number by powers of 10 so that the first digit in the number is between 1 and 10. So 0.000714 = 7.14 x 10-4

20 is the smallest number that both 4 and 10 will divide into evenly with no remainder.

A prime number is a number that has only 1 and itself as factors. (only 2 factors) This means, only 1 and that number can evenly divide into the number you're talking about. For example: 7 is prime because the only numbers that divide into 7 are 1 and 7. 10 is NOT prime, because I can divide 1, 2, 5, and 10 into it. it has 4 factors (more than 2) so it is not a prime number. 10 is called a composite number. A number that is not prime is composite.
You divide 4 by 10.

Math Factors are numbers that divide evenly into another number. For instance 10-the factors would be 1,2,5 and 10 . All numbers divide evenly into 10.
50, 20, 25, 10, 5, and 12.5 don't divide into 4 but all of them divide into 400. There is no number that I can think of that is not a factor of 400 but is a factor of 100 as 100 is a factor of 400, so whatever number makes up 100 must make up 400.
