Express 125/1000 as a decimal.

Explanation:
When a fraction has a denominator that’s a power of ten, you can convert it to a decimal by moving the decimal point in the numerator to the left the same number of places as there are zeros in the denominator. Here, 1000 has three zeros, so move the decimal three places left in 125—giving 0.125. You can also see this by simplifying 125/1000 to 1/8, and 1/8 equals 0.125. So the decimal form is 0.125. The other values would come from different denominators, so they don’t match this fraction.
