Answer:
15/56
Step-by-step explanation:
To get the answer, you find the least common denominator of 4 and 7 which is 28. 1/4 is equal to 7/28. 2/7 is equal to 8/28. if you subtract 7/28 from 8/28, you get one twenty-eighth (1/28). Half of 1/28 is 1/56. To add 1/56 and 7/28, multiply the numerator and denominator of 7/28 by 2. You will get 14/56. Add 14/56 and 1/56 and the answer is 15/56. I'm pretty sure this is the answer. Thanks!
