Simplest way to put it...find the largest number that will go into both the numerator (top #) and the denominator (bottom #) evenly. The number is called the greatest common factor (GCF). If you can't find the GCF, then just start off with small numbers like 2, 3, 4. When you get better at it, then you can start using larger numbers.

Ex. Look at the fraction 4/12...well I know that 2 will go into 4 and 12. 4 divided by 2=2 and 12 divided by 2= 6. So, now you have the fraction 2/6. Ask yourself "is there any other number other than 1 that can go in 2 and 6 evenly?" Your answer should be "Yes, 2 can!" Now, 2 divided by 2=1 and 6 divided by 2= 3. Your new fraction is 1/3! Ask yourself that same question. This time, your answer should be "No!"

Your fraction is now in simplest form. When you get better at this, then you can start looking at fractions and instantly know the GCF. The GCF in my example is 4. We could have started with 4 saying 4 divided by 4=1 and 12 divided by 4=3. As you can see, you will still get 1/3 as your answer.

I hope this helps.

To reduce fractions to lowest terms, you need to multiply the numerator(top) and denominator(bottom) by the same number. For example 4/16, I can divide both 4 and 16 by 4 so it would be 1/4. But for 5/16, they can't be divided by a same number so it is in lowest terms.

Examples would be the best.

3/6 = 1/2

7/21 = 1/3

Is this what you are looking for?
