EQUIVALENT DECIMALS
To compute with decimals, an understanding of equivalent decimals is a must. We will first examine some equivalent decimals and how adding and taking away zeros at the end of a decimal number does not change the value of the number.
DECIMAL COMPUTATIONS - ADD, SUBTRACT, AND MULTIPLY
To add and subtract decimals, often times it is necessary to write an equivalent decimal before computing. Remember: line up the decimals when adding and subtracting.
To find the product of two decimals, multiply the decimals. It is not necessary to line up the decimal points. We place the decimal point by counting the number of decimals places to the right of the decimals. We will practice multiplying decimals less than one in value, and practicing multiplying decimals greater than one which includes multiplying by a three-digit number.
