What are the rules for multiplying decimals?
Multiply the numbers without the decimal points.Count the total number of digits after the decimal point in the original numbers and put the decimal point into the answer so that there are the same number of digits after the decimal point.Examples:2.4 x 3.24do 24 x 324 = 7776 There is one digit in 2.4 and two in 3.24 after the decimal points making three digits in total, so insert the decimal point into the answer so that there are three digits after it: 7776 → 7.776⇒ 2.4 x 3.24 = 7.7762.5 x 3.26do 25 x 326 = 8150 There is one digit in 2.5 and two in 3.26 after the decimal points making three digits in total, so insert the decimal point into the answer so that there are three digits after it: 8150 → 8.150⇒ 2.5 x 3.26 = 8.152.5 x 0.02do 25 x 2 = 50 There is one digit in 2.5 and two in 0.02 after the decimal points making three digits in total, so insert the decimal point into the answer so that there are three digits after it: 50 → 0.050⇒ 2.5 x 0.02 = 0.05
