I need help with improper fractions may you please help me thanks
An improper fraction is simply a fraction with the numerator being larger than the denominator.

To make it an improper fraction from the mixed number given, just multiply the whole number (2) by the denominator (3), then add the numerator (2). The result is the new numerator and the denominator remains the same.

In this case (2 2/3), it would be 2 * 3 + 2 for the numerator....or 8. So 8/3 would be the improper fraction.

What are improper fractions equal to 4 2/3?
I think of pizzas when doing fractions. If you cut the four full pizzas into thirds, how many slices will you have? Add this to the two other slices and you get your improper fraction.

So, to make an improper fraction, you multiply the whole number by the denominator and add it to the numerator. To get more improper fractions, you can multiply the numerator and denominator by the same number.

How do you enter mixed numbers ( whole numbers and fractions i.e 3 3/4)?
You cannot, you must enter 3.75. If you can't figure out what the fraction is, you must first compute the fraction (3/4=.75) and then add it to the whole number (3+.75=3.75)

Answers show in fraction form. how do i switch it
I know that you can press the S↔D just above the DEL key. By pressing this key the answer will toggle between fraction and decimal display. As far as locking the calculator into a mode that will default to decimal results, well... that's why I'm here looking.

Fraction button directions
Yeah, there isn't a fraction button on an 84. You have to enter it manually as 4/9 or if simplifying a decimal, use the Ans>Frac under the MATH menu
