## Multiplying Decimal Numbers

If you can multiply numbers you can multiply decimals. It is only a matter of, once you have multiplied two numbers, of counting the number of decimal places.

Example:

0.3*0.2

3*2=6

0.1 has one number after the decimal point and 0.2 has one number after the decimal point so there are two numbers after the decimal point in the answer.

The answer is 0.06

Example

0.29*27

 * 20 9 20 400 180 7 140 63

400+180+140+63=783. In the question there are two numbers after the decimal point for 0.29 and two numbers after the decimal point for 0.27 so there will be four numbers after the decimal point in the answer. The answer is 0.0783.

420*0.232

 * 400 20 200 80000 4000 30 12000 600 2 800 40

80000+4000+0+12000+600+0+800+40+0=97440

In the question there are no numbers after the decimal point for the 420 and there are three numbers after the decimal point for the 0.232 so there are three numbers after the decimal point in the answer. The answer is 97.440=97.44

43000*0.059

 * 40000 3000 50 2000000 150000 9 360000 27000

2000000+150000+360000+27000=2537000

There are no numbers after the decimal point for 43000 and 3 numbers after the decimal point for 0.059 so there are three numbers after the decimal point in the answer. The answer is 2537.000=2537
