1/2, 1/4
CD is 2.
The common denominator is 4
To add one half and three quarters, you first need a common denominator. The common denominator for 2 and 4 is 4. Converting one half to quarters gives you two quarters, so when you add two quarters and three quarters, you get five quarters, which can also be expressed as one and one quarter (1 1/4).
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.
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.
