To simplify a fraction, divide the numerator and the denominator by their GCF.
Example: 30/42
The GCF of 30 and 42 is 6.
6 into 30 is 5
6 into 42 is 7
30/42 = 5/7

When reducing fractions to their lowest terms
Yes, fractions can be ordered from lowest to highest. It's called "ascending order."
Knowing the LCM will help when adding or subtracting unlike fractions. By finding the LCM of the denominators, (called the lowest common denominator) you can convert unlike to like fractions and proceed with the adding or subtracting. Knowing the GCF helps reduce a fraction. By finding the GCF of the numerator and the denominator and dividing both of them by it, you can reduce a fraction to its lowest terms (simplest form). If the GCF is 1, the fraction is in its simplest form. You can successfully multiply fractions without knowing the GCF or LCM.
Poem To Divide Fractions :Dividing fractions is easy as pie flip the second then multiply !~Never flip the first!!!!!!!!!!Ex: 1/7 Divided by 1/5 = 1/7 Divided by 5/1 < you flip the second= 5/7Then Simplify(if told) till you cant simplify No more. :)Inverse the divisor and multiply as for example 3/4 divided by 3/5 becomes 3/4 multiplied by 5/3 = 15/12 or 5/4 in its lowest terms
