Step-by-step explanation:
Multiplying and Dividing Decimals
The decimals are non-whole numbers. A decimal poi nt is used followed by digits that represent a value that is less than one. To solve for n of the given equations above, you have to multiply and divide the decimals. Below are the rules that you have to remember when multiplying and dividing decimals.
- When multiplying decimals, you have to multiply the numbers, ignoring the decimal poi nts. Then, the number of decimal places in the product depends on the total number of decimal places in the factors.
- When dividing decimals, you have to get rid of the decimal poi nt first before you divide. To get rid of the decimal poi nt, start with the divisor. Move the decimal poi nt to the right until you get a whole number. Then, do it also to the dividend. Move the decimal poi nt depending on the number of moves you made with the divisor.
