multiply the numerator and the denominator by the same number, or divide each side by a common factor.
two equivalent fractions for 5 over 15 = 1/3, 10/30
To find out if two fractions are equivalent, either reduce them both to their simplest forms (which will be the same number if they're equivalent) or convert them to decimals (which will be the same number if they're equivalent). To make an equivalent fraction of a given fraction, multiply the numerator and the denominator of the given fraction by the same counting number.
You can convert them to equivalent fractions with like denominators, then simply compare the numerators.You might also convert each fraction to a decimal (divide the numerator by the denominator); then you can also compare them.
If doing it without a calculator, then convert each mixed fraction into a top-heavy equivalent fraction and then multiply as for fractions.
