Tasha, Tess and Trudy need to spend a total of 60hrs. over the next year to complete a project in their appartment. How much time will Trudy spend if they have agreed to split the time in the ratio 7 to 4 to 9, respectivley?
I have no idea how to even start.
Of 20 hours, Tasha, tess, and Trudy will spend 7;4;and 9 hours each.
How many 20 hrs are in 60?
30 hours
No. There are three 20's in 60.
so trudy= 3*9
To solve this problem, you need to divide the total time (60 hours) according to the given ratio (7:4:9) and find the share of Trudy. Here's how you can do it:
Step 1: Find the total parts in the ratio
Add up the three parts of the ratio: 7 + 4 + 9 = 20. This ratio represents the total number of equal parts, indicating the total contributions from Tasha, Tess, and Trudy.
Step 2: Determine the share of Trudy
Since Trudy's share is represented by 9 parts out of 20, we need to calculate that proportion:
Trudy's share = (Trudy's part / Total parts) * Total time
Trudy's share = (9 / 20) * 60
Trudy's share = 27 hours
Therefore, Trudy will spend 27 hours on the project.
