How to Make the Denominators Common?
There are two simple steps to get a common denominator for a given set of fractions.
- Step 1: Find the Least Common Multiple (LCM) of the denominators of the fractions.
- Step 2: Multiply the fraction with an appropriate number, such that the denominators of the fractions are equal to the LCM value.
Find the common denominator for 3/4 and 1/6.
The given fractions are 3/4 and 1/6.
The LCM of 4 and 6 = 12. Now, let us use this LCM.
In the first fraction, the denominator is 4. Now, we will have to check the number that we need to multiply this 4 by, to make it 12 (12 ÷ 4 = 3, here it's 3). Therefore, we multiply 3/4 by 3 so that the fraction becomes 9/12
In the second fraction, the denominator is 6. Again, we will have to check the number that we need to multiply this 6 by, to make it 12 (12 ÷ 6 = 2, here it's 2). Therefore, we multiply 1/6 by 2 so that the fraction becomes 2/12
Hence, we get 9/12 and 2/12 which have a common denominator 12 and they are the equivalent fractions of 3/4 and 1/6 respectively.
