FutureStarraWhat Is the Fraction Button on a Scientific Calculator
A scientific calculator is essentially an inverted calculator. You can use the number pads to work out fractions, just like you would with an ordinary calculator.
Calculators that display fractions sometimes have a special mode, called Math mode, that you must first select before you can enter fractions. When the calculator is in Math mode, the word "math" appears at the top of the screen. Once you have selected this mode (if necessary), look for a button with two boxes, one black and one white, arranged on top of each other with a horizontal line between them. This is the fraction button. On some models, the button may show x/y or a b/c. Pressing this button enables the fraction feature.
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)
