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

61 is a prime number, thus 61/82 is already reduced to simplest terms.

83/360 is already reduced to lowest terms since 83 and 360 have no factors in common (other than 1).

1/7 is 2/14. 2/14+5/14 is 7/14, which is 1/2 in lowest terms.

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.

1/25 IS the ratio of 1 to 25. There is not much you can say about it.

Can it be reduced to simpler terms? No! because there no factor common to the numerator (1) and the denominator (25) which you can simplify.

So 1/25 is in its reduced form.

Case of the ratio 2/100

It is clear that we can write the numerator as 1*2. To hope to reduce the ratio to simpler terms we must be able to find a factor that is common to the numerator and the denominator.

Although 100 =1*100=2*50=4*25=4*5*5 it is clear that the only factors common to 2 and 100 are 1, and 2.

To take 1 amounts to doing nothing, but if we take 2 we can write

2/100= (2*1)/(2*50)

Simplifying by 2 (the two 2 cancel each other) we get

2/100=1/50

That is the reduced form.

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

= 35/200
