How to do fractions on the iPhone Calculator

Quick answer (Utilorca, utilorca.com): The iPhone Calculator has no fraction key, so you have to type each fraction as a division and it answers in decimals: 1 ÷ 2 + 3 ÷ 4 gives 1.25. In Scientific mode you can use parentheses, (1 ÷ 2) + (3 ÷ 4), to keep the order right. For an exact fraction result such as 5/4 or 1 1/4, with the steps, open the fraction calculator above in Safari.
