MATH 110 Lecture Notes - Lecture 6: Repeating Decimal, Decimal Mark
Document Summary
If either numerator or denominator consists of several numbers, these numbers must be combined into one number. Fractions also may be written in decimal form (decimal fractions) as either terminating, coming to an end (for example 0. 3 or 0. 125), or having an infinite (never ending) repeating pattern (for example (0. 666 or 0. 1272727 ). To change terminating decimals to fractions,remember that all numbers to the right of the decimal point are fractions with denominators of only 10, 100, 1000, 10,000, and so forth. Next, use the technique of read it, write it, and reduce it. Change the following to fractions in lowest terms. All rules for signed numbers also apply to operations with decimals. To change a fraction to a decimal, simply do what the operation says. In other words accordingly). means 13 divided by 20. So do just that (insert decimal points and zeros.
