You can compare fractions by entering the fraction enclosed with square brackets. For example, to compare 1/7 and 1/8, enter Compare [1/7], [1/8]. The result will be returned as 1/7 > 1/8. Using the square brackets keeps the fractional representation, otherwise it would be converted to a decimal. For example, entering Compare 1/8, [1/8] will return a result of 0.125 = 1/8.
