To add unlike fractions you need to make them have a common denominator. If you want to learn more about fractions or elementary math you can try Smartick for free. The fraction 26 is equal to 13 when reduced to lowest terms.

While you could just multiply the numerators and the denominators it will be easier to do the math if you can simplify the fractions first. Lets suppose that we want to add the following two rational. Adding and Subtracting Fractions.

So in order for it to be hundredths your answer needs to have two decimal digits. Over the last few pages youve learned how to multiply fractions. 67 25 6 5 2 7 30 14 16.

Two frations are equivalent when they have the same value when written in lowest terms. If two fractions are given we can simply find their decimals to check if.

Cross-cancellation makes fractions easier. Section 5-5. Of means you should multiply so you need to solve 13 38.

To solve 6 005 you can multiply 6 5 30 in your head. To find equivalent fractions just multiply the numerator and denominator of that reduced fraction 13 by any interger number ie multiply by 2 3 10 30.
