How To Add Four Fractions With Different Denominators

How To Add Four Fractions With Different Denominators. Using a rectangle as the unit, we divide them into 2, 3, and 4 parts, and in this case, each is a different color. To add fractions with unlike denominators, start by finding the least common multiple for the denominators.

You can use this method to add or subtract fractions: Multiply the numerator with the factor needed to come up with the least common. Let’s look at an example:

Add The Top Numbers (The Numerators ), Put That Answer Over The Denominator.


For example, consider this series of three terms: Use the equivalent fractions property to multiply the numerator and denominator by the number from step 2. Write the given whole number in the form of a fraction (for example, 3/1) make the denominators same and add the fractions.

Make Sure The Bottom Numbers (The Denominators) Are The Same.


For each fraction, determine the number needed to multiply the denominator to get the lcd. You can add and subtract 3 fractions, 4 fractions, 5 fractions and up to 9 fractions at a time. Take the number you get for each fraction and multiply it by the numerator and denominator of that fraction, which will make both denominators equal to the least common.

Using A Rectangle As The Unit, We Divide Them Into 2, 3, And 4 Parts, And In This Case, Each Is A Different Color.


The lowest common multiple (lcm) of a series of terms is the smallest product that contains every factor of each term. Click the calculate button to solve the equation and show the work. Multiply the top number on.

To Add Fractions There Are Three Simple Steps:


Simplify the numerator and denominator. To understand this problem correctly, we have graphically represented each addend: Multiply the two terms on the bottom to get the same denominator.

Find The Least Common Denominator.


Let's do one more of these. What is this going to be? 3/9 + 1/6 = the first step is to find the lowest or least common multiple of our denominators, which in this example are 6 and 9.
