Answer:
It’s c
Step-by-step explanation:
I just did it
2/7 - 5/21 = 6/21 - 5/21 (find common denominator first, then subtract)
6/21 - 5/21 = 1/21
3/4 = 63/84
5/7 = 60/84
7/12 = 49/84
63/84 + 60/84+ 49/84 = 172/84
172/84 - 4/84 = 168/84
The answer is 168/84, or 2. Hope this helped!
Answer:
The ratio in which the amount is shared is 16:19:13
Step-by-step explanation:
The given parameters are;
The number of days Henry worked = 8 days
The number of days Jack worked = 9.5 days
The number of days Steffi worked = 6.5 days
The sharing formula for the amount earned for the project = The ratio of the number of days worked by each one
The total number of days worked by all three = 8 days + 9.5 days + 6.5 days = 24 days
The fraction of the total number of days Henry worked = (8 days)/(24 days) = 1/3 = 16/48
The fraction of the total number of days Jack worked = (9.5 days)/(24 days) = 19/48
The fraction of the total number of days Steffi worked = (6.5 days)/(24 days) = 13/48
Therefore. the ratio in which the amount is shared = 16:19:13 (which is the same as the ratio of the number of days worked)
