How to Put a Fraction Into a Phone Calculator
Fractions are a confusing concept. In is fraction class, students learn to identify fractions and write them as ratios and products of numbers, but what if they have a problem they just can't solve on the fly?
Pick which calculator you want to use. The web page has several different calculators you can use. If you are solving simple fractions with no whole numbers, use the first calculator at the top labeled "Fraction Calculator". If you need to solve equations that involve whole numbers and fractions, use the "Mixed Numbers Calculator." It's the second calculator from the top of the page..Enter your numbers. If you are using the basic fractions calculator at the top, enter the numerators (top numbers) for your fractions in the top boxes. Then enter the denominators {bottom numbers) in the boxes on the bottom. If you are using the Mixed Numbers calculator, write your numbers in each box with the whole number in front followed by a space at the beginning. Then enter the numerator followed by a slash and then enter the denominator (i.g. "1 3/4"). By default, scientific calculators, like regular ones, display fractions as decimals. So if you enter a simple fraction, such as 1/2, the display reads 0.5. Some – but not all – scientific calculators offer a feature that allows you to display fractions without making the conversion. Using this feature, you can enter a complex fraction and simplify it right on your calculator. Calculators with this feature also allow you to enter a number composed of an integer and a fraction, such as 1 1/4. If your calculator doesn't have this feature, you can use a workaround to manipulate fractions.

If your calculator doesn't have this feature, you can use a workaround to manipulate fractions. You can't convert a decimal to a fraction on the calculator, but the calculator can help you do it with a pencil and paper. Suppose you want to express 0.7143 as a fraction. You could write it as 7143/10,000, but maybe you want to reduce this to something a lot more simple, such as a denominator that's a single digit. To do this, enter the original number as decimal, and then multiply by the desired denominator. This gives you the numerator of the fraction. For example, if you want a fraction with 7 in the denominator, multiply 0.7143 by 7. The calculator will display the numerator, which in this case is 5.0001, which is close enough to 5 to be equal. You can then write the fraction 5/7 on a piece of paper. (Source: sciencing.com)
