The common denominator is 4
First, find a common denominator. 1 is the same as 4/4. A half is the same as 2/4. And 1 quarter (.25) is the same as 1/4. So, since they are now all over a denominator of four, simply add the numerators and reduce. 4+2+1=7. 7/4 is your answer, or 1 3/4.
2 Convert 1/2 to 2/4, then 4 will be the common denominator.
It is 4.
By converting to a common denominator (convert 1/2 to twelfths), and comparing. Because 5 is less than half of 12.
One half plus a quarter can be calculated by converting both fractions to have a common denominator. In this case, the common denominator is 4. Therefore, one half is equivalent to two fourths. Adding two fourths to one fourth gives a total of three fourths. So, one half plus a quarter is equal to three fourths.
The common denominator is 4
3/4 Because a half (½) and a quarter (¼) have different denominators, to add them you find need to find their least common denominator. Fortunately that's easy because 2 is a factor of 4. A half is equivalent to two quarters; adding a third quarter gives a total of ¾.

The least common denominator is 6.
1/2 = 3/6 1/3 = 2/6 so your common denominator would be 6
Answer: You can use a calculator Answer: You must convert to a common denominator - just as when you add fractions. In this case, the common denominator is 6.
