Mathematical Rules and Guidelines

- Mathematical Rules and Guidelines (continued) Function Dividing decimals Convert a decimal to a fraction Rules 0 If your number is not a whole number, move the decimal point of the divisor the necessary number of spaces to make the divisor a whole number, I If the dividend has a decimal, move it to the right the same number of places as you moved the divisor‘s decimal point. - Add zero (0) placeholders as necessary. 0 Divide as usual, and then move the decimal directly up in the quotient. 0 Simply place the entire number over the value of the decimal placeholder of the last digit of the number. I Remember to reduce the final answer to its simplest terms. Example 56.42 + 9.1 = Steps: 1. )9.156.42 U 2. 9 )56.42 L) 3. 6.2 905642 5461 182 g 0 Convert 0.75 to a fraction. Steps: A 100 - Note: The 5 is located in the hundredths placeholder, thus 75 is placed over 100.
