0.151/1 Rewrote equation as fraction.
To finish off the problem, we need to get rid of the decimal point in the numerator. To do that, we have to move the decimal point three places to the right, so that it occurs right after the '151'. And in order for us to do that, since we have to move the decimal point THREE places to the RIGHT, we must multiply the numerator by 10^3, or 1,000. But by doing that, as a rule of fractions, we have to multiply the denominator by the same value.
(0.151 * 1000)/(1 * 1000) = 151/1000
Now, if we had to move the decimal point to the left, the number in the power of 10^x would be negative.
