How do you subtract fractions??

Question

14. ¾ - ½ =

A. ¼

B. 1/3

C. ½

D. 2/3

E. 2/5

Answer 1

like addition you must find a least common denominator

  

3/4-1/2=  3/4 -2/4 =1/4   4 is the lcd of 2 and 4    A

Answer 2

A = 3/4 - 1/2

=> A = 3/4 - 2/4 = 1/4

The key to solve fractions is to get a common denominator

Answer 3

The answer is option A 1/4

First find LCM of the denominators of both fractions. And subtract numerator of small no. from greater no.

Answer 4

For fractions with the same denominator such as 4/4-3/4 you just subtract the top number leaving you with 1/4. For this question you need to find a common denominator between the two fractions. Since the first fraction is in fourths you can turn the second faction in fourths as well which makes the question 3/4-2/4 which equals A:1/4

Answer 5

Find the Lowest common denometor  (the bottom nuimber)

  3/4 - 1/2  the LCD is 4  so  multiply your second fraction by 2  ( 2x 2 =4(

3/4- 2/4  now you just subract the top numbers (3-2=1)  

your answer will be 1/4
