Explain the multiplication of decimal numbers.
Multiplication of Decimals:
1. Multiply normally, ignoring the decimal points.
2 Put the decimal point in the answer. It will have as many decimal places as the two original numbers combined.
For example,
$12.1 \times 4.2$
step 1. $121 \times 42 = 5062$
Number of decimals in both the numbers combined $= (1+1) = 2$
step 2. $12.1 \times 4.2 = 50.62$.
