8.3521e^-4 make it a fraction

This answer is correct. 4/12 divided by 2/2= 1/3
The reciprocal of 2/2 is 2/2
Then you multiply straight across and reduce to get 1/3

Add

0.2666666.....

It is simple. 36=4x9 and 63=7x9. The number 9 is a common factor in both numbers. You can simplify the fraction by dividing both the numerator and the denominator by 9.
36/63=(4x9)/(7x9). You can rewrite the fraction as (4/7)*(9/9)=4/7 because 9/9=1.
The reduced fraction equivalent to 36/63 is 4/7. Since 7 and 4 have no common divisor you cannot reduce the fraction further.

First of all, know the following basic rule about fractions and whole numbers:

4 / 4 = 1

Therefore:

( 31 X 4 ) / 4 = 31

Therefore:

124 / 4 = 34

So:

34 and 1/4 = (124 / 4) + (1 / 4) = 125 / 4


Therefore 31 and 1/4 can also be expressed as the following FRACTION: 125 / 4.



If you are trying to convert that to a DECIMAL value instead, then 31 and 1/4 % = 31.25 %



Good luck, I hope that helps.

This calculator is incapable of displaying simplified fractions (i.e. 1 ½), you will have to use the decimal value or contain your complex fraction in parenthesis. (i.e. (5/2).)

find the least common denominator between the original fraction into the new fraction.
example, 1/2 to 2/4 to 4/8 to 8/16.

Place both the base and the exponent in parentheses

(3/4)^(-2) then press enter. Your answer will be in decimal form at first 1.777...

Press MATH
Select the 1: Fraction option and it will convert your decimal value to the fraction answer of 16/9.

Negative exponents flip the fraction. For instance, (3/4)^(-1) = 4/3. So for (3/4)^(-2) you could just square the numerator and denominator separately to get 9/16, and then flip the fraction to account for the negative. That will give you 16/9.

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

use the "carrot" button, ^. Type in 4^.5 and you get 2. If you are going to use fractions, use the division bar and parenthesis and not the fraction key. Example 4^(1/2) = 2
