To convert a fraction to lowest terms, we must divide the numerator (the top number) and the denominator (the bottom number) by a common number until we can't reduce it any more. A method for doing this is to factor the numerator and denominator by their common factors.

So let's factor 711 and 22.

1 x 711

9 x 79

3 x 3 x 79

I don't think I can factor 79. We should check the numbers from 2 up to the square root of 79, or approximately 9.

Factoring 22,

1 x 22

2 x 11

Unfortunately, none of the factors of 711 are common with the factors of 22, so it is already in its lowest terms, and cannot be reduced.

Good luck,

Paul

The fraction 711/22 is an improper fraction (the numerator is greater than the denominator).

While there is nothing incorrect about this, an improper fraction is typically simplified further into a mixed number.

The whole number part of the mixed number is found by dividing the 711 by the 22. In this case we get 32.

The fractional part of the mixed number is found by using the remainder of the division, which in this case is 7 (711 divided by 22 is 32 remainder 7).

The final answer is: 32 7/22

### How to convert percent to fraction

1% = 1/100

So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.

For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:

56% = 56/100 = 14/25

- Divide the percent by 100 to get decimal number.
- Count the number of digits (d) to the right of the decimal point of the decimal number.Example: 2.56 has 2 digits to the right of the decimal point, so d=2.
- Calculate the factor (f) for making the decimal number an integer:
*f*= 10*to power d*

Example:

*f*= 10 power 2 = 100

- Multiply and divide the decimal number x by the factor f:
*x***f*/*f*=*y*/*f*

Example:

2.56 * 100 / 100 = 256 / 100

- Find the greatest common divisor (gcd) of the fraction.
Example:

gcd(256,100) = 4

- Reduce the fraction by dividing the numerator and denominator by the gcd value:
Example:

256 / 100 = (256/4) / (100/4) = 64/25

1% = 1/100

So in order to convert percent to fraction, divide the percent by 100% and reduce the fraction.

For example 56% is equal to 56/100 with gcd=4 is equal to 14/25:

56% = 56/100 = 14/25

This arrow indicates that the displayed fraction is not in its simplest terms. See pages 17-18 of the user manual.

You have to be careful. 80% is in fact 0.8.

Turn the calculator ON.

Enter the number 0.8

If your calculator is set to Write-View you will see the number displayed as a stacked fraction 4/5. If it is already in this form, press the key marked**change** with two arrows. The display should show a fraction.

If your calculator is set to LINE, you will see 4r5, where 4 is the numerator and 5 is the denominator.

**The key marked change allows you to change displayed result from decimal to fraction and from fraction to decimal. When a number is converted to a fraction, it will always be a fraction reduced to its simplest terms.**

(4 1/3) / (1 2/3) = (make the two numbers proper fractions)

(13 / 3) / (5 / 3) = (the "/ 3" on the left and right cancel out each others)

13 / 5 = (go to lowest term)

2 3/5

(13 / 3) / (5 / 3) = (the "/ 3" on the left and right cancel out each others)

13 / 5 = (go to lowest term)

2 3/5

Transforming 0.175 to fraction:

= 175/1,000

Reduce to lowest term (divide by 5 both the numerator and the denominator):

= 35/200

Reduce further by dividing both by 5:

= 7/40

This is the lowest terms now that it can't be reduced further.

The "Other" way round, Bottom number into ONE and multiply it by the Top. EG: 3/4 == 1 divided by 4 = 0.25, now we multiply, .25 by the Top number or in this case 3, that equals 0.75. 1/4 =0.25 x 3 = .75. 3/4 is the same as 0.75.

= 175/1,000

Reduce to lowest term (divide by 5 both the numerator and the denominator):

= 35/200

Reduce further by dividing both by 5:

= 7/40
