How to Multiply and Divide Decimals Like a Pro
Multiplying and dividing decimals follow the same rules as whole numbers, with one key exception: decimal places must be aligned correctly. When multiplying decimals, the product will have as many decimal places as the total number of decimal places in the factors. For instance, multiplying 4.2 by 5.6 will result in 23.52. Conversely, when dividing decimals, the quotient will have the same number of decimal places as the dividend.
