The greatest common factor of 84 and 42 is 42. Of course, the term refers to the largest number which is evenly divisible into the givens. So, since 2 X 42 = 84 and 1 X 42 = 42, and since there can be no factor of any number which is greater than that number itself, the gcf of 84 and 42 must be 42. Good luck. Truly.

### What is the improper fraction of 2/10

I think you want to reduce the fraction to the lowest terms.

Improper fraction 1 3/4 produces an improper fraction of 7/4 (1 times denominator plus numerator)

To reduce a fraction, we need to divide the numerator (number on top) and the denominator (number on the bottom) by the greatest common factor (GCF).

To get the GCF, find the factors of the numerators and denominators and find the greatest number that is in both lists.

The factors of 2 are 1, 2.

The factors of 10 are 1, 2, 5, 10.

The greatest (largest) number is both lists is 2, so we divide the numerator and denominator by 2 and get 1/5.

Good luck,

Paul

### How do i simplify ratios using casio scientific calculator fx-991ms

If you enter the ratios using the fraction entry key ( [a b/c] the results will be displayed as fractions. And when the calculator displays fractions they are always in their reduced form.
In general, when you are manipulating fractions ( Pi/2 is no a fraction even if you write it as one) you can try to simplify them by looking for the greatest common factor (GCF) of the numerator and denominator. When you simplify by the GCF the fraction that is left is in its reduced form.

### How to find G.C.F. on a TI-30xIIs calculator?

I don't think there's specific key for this but you can do it this way:

1. Divide those 2 numbers for which you want to find gcf
2. If you get result as decimal number press keys [2nd][PRB] to display it as fraction
3. Also if fraction you get is in form a b/c (ex. 1 2/3) you have to convert it to form d/c (for 1 2/3 that would be 5/3)
4. Greatest common factor is then 1st number divided by numerator (or 2nd number divided by denominator)
For example:
• You want to find greatest common factor of 30 and 18.
• You divide them: you should get 5/3 (after converting result to fraction of form d/c, as described in steps 2 and 3).
• This means that 30/18=5/3=5x/3x (x is gcf here).
• Now you know that x=30/5=18/3=6 so greatest common factor is 6.

I hope this helps :)
