Knewton GMAT is a GMAT prep course that redefines everything you thought you knew about online learning. We're about to talk about multiplying decimals. Whenever we multiply numbers that have decimals in them, we're going to follow this three-step process. 1. Multiply without decimals. 2. Count the total number of digits to the right of the decimal place in the factors. 3. Move the decimal point to the left as many places as you counted in step (2) Let's take a look at an example. 0.25 x 10.1 Step 1. Multiply them as if they did not have decimals. 25 x 101 = 2525. Step 2. Count the total number of digits to the right of the decimal place in the factor. There are two digits to the right of the decimal point in 0.25 and one digit to the right of the decimal point in 10.1 for a total of three digits behind the decimal points. Step 3. Finally, we're going to move our decimal point back three spaces because three was our total as counted above. Our answer from 2525 then becomes 2.525.
