Multiplying Decimals: 0.2 x 0.25
Multiplying decimals can seem intimidating, but it's actually a pretty straightforward process. Here's how to find the product of 0.2 and 0.25:
Step 1: Ignore the decimal points
Start by ignoring the decimal points and multiplying 2 and 25 as if they were whole numbers:
2 x 25 = 50
Step 2: Count the decimal places
Now count the total number of decimal places in the original numbers. 0.2 has one decimal place and 0.25 has two decimal places, for a total of three decimal places.
Step 3: Place the decimal point
Place the decimal point in the product (50) so that it has the same number of decimal places as the total from step 2 (three decimal places):
0.050
Therefore, 0.2 x 0.25 = 0.050 or simply 0.05.
Let's understand why this works:
Decimals represent fractions with a denominator that is a power of ten. For example, 0.2 is equivalent to 2/10 and 0.25 is equivalent to 25/100.
When we multiply fractions, we multiply the numerators and the denominators.
So, 0.2 x 0.25 is the same as:
(2/10) x (25/100) = (2 x 25) / (10 x 100) = 50/1000
50/1000 can be simplified to 5/100, which is equivalent to 0.05.
