You divide the numerator (top) by the GCF to give you the numerator for the reduced fraction. You divide the denominator (bottom) by the GCF to give you the denominator of the reduced fraction. DONE!
For example, 27/45
GCF(27, 45) = 9
Numerator of reduced fraction = 27/9 = 3
Denominator of reduced fraction = 45/9 = 5
So reduced fraction = 3/5

How do you reduce fractions into lowest terms?
Find the GCF of the numerator and the denominator. Divide each of them by that number. If the GCF is 1, the fraction is already in its lowest terms.
How do you convert a decimal into a fraction and then reduce?
One way to convert decimals to fractions is to say them out loud. 0.45 is forty-five hundredths, or 45/100. We reduce fractions by taking the GCF of the numerator and denominator. The GCF of 45 and 100 is 5. Divide both numbers by 5 and get 9/20.
How do you simplify fractions using the factor tree?
To simplify fractions, it is necessary to divide the numerator and the denominator by their GCF. You can find their GCF by comparing their prime factorizations. You can find their prime factorizations through the use of factor trees.
How do you put a fraction into gcf?
The GCF refers to integers, not fractions. You can find the GCF of the numerator and denominator of a fraction (if they are integers), but you will not be able to find the GCF of two fractions.
How do you get the lowest terms of fractions?
Find the GCF of the numerator and the denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.
