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.
What problems can be solved using gcf and LCM?
Finding the LCM will make adding and subtracting fractions easier.
How does finding the gcf help you solve real world problems?
Finding the LCM will help you add and subtract fractions. Finding the GCF will help you reduce fractions.
How do GCF and LCM involve with the real world?
Use the GCF to reduce fractions. Use the LCM to add and subtract unlike fractions. Carpenters work with fractions a lot.
What does GCF mean in fractions?
GCF doesn't apply to fractions, only to whole numbers. When those numbers are the numerator and denominator of a fraction, the GCF can be used to reduce it to its simplest form.
Why is greatest common factor in math helpful?
Finding the GCF helps to reduce fractions to their simplest form. Knowing the GCF can help to find the LCM, which assists in adding and subtracting fractions.
How can knowing the GCF and LCM help you when you add subtract and multiply fractions?
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.
Why problems can be solved using gcf?
Reducing equivalent fractions to their simplest form.
What does greatest common factor do?
The GCF is the largest number common to a given set of two or more numbers. Finding the GCF helps you to reduce fractions.
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 can fractions be simplified by finding the GCF and using divisibility rules?
Simplifying fractions and finding the GCF is easy. All you have to do is put the fraction into simplest form and then put in a whole number.
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.
What types of problems can be solved using the greatest common factor and what types of problems can be solved using the least common multiple.?
Finding the GCF will help in simplifying fractions. Finding the LCM will help in adding and subtracting fractions.
