The morning temp. In Atlanta, Georgia is 21 1/4 degrees. During the day it warms up 6 2/7 degrees. What is the new temp

Answer:27 15/28 degreesStep-by-step explanation:Since we are adding 21 1/4 to 6 2/7, we need to find the LCD, or, least common denominator, so that we can add 1/4 and 2/7 together. 1*4=4             1*7=72*4=8           2*7=143*4=12          3*7=214*4=16          4*7=285*4=206*4=247*4=28Since we had to multiply 7 four times to get it equal to 28, we need to take 2/7 * 4/4. This will give you 8/28. Then, since we multiplied 4 seven times to get it equal to 28, we need to take 1/4 *7/7. This will give you 7/28. Finally, you need to add 8/28 and 7/28 since they now share the same denominator.8/28 + 7/28=15/28For our last step, we need to add the whole numbers together so the answer is complete.21+6=2727+15/28= 27 15/28 degrees
