Changing 80% to a fraction in the lowest term

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,

There are an infinite number of fractions equivalent to 6/8. Reduced to lowest terms, it's 3/4. Some others include 9/12, 12/16, 30/40, 60/80, 75/100, 300/400, 600/800, and 6000/8000. As a percentage, it's equal to 75%.

5/6 is 15/18, 1/9 is 2/18, so 15/18 - 2/18 is 13/18 .

As a fraction, 45/90. In lowest terms, 1/2. As a percentage, 50 or 50%.

(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

61/82 is already reduced to lowest terms since 61 and 82 have no factors in common (other than 1). In fact 61 is a prime number so it has no factors other than 1 and 61.

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.

multiply each by 5 to get whole numbers. your ratio will be 35:26

7/9 is the lowest
