Answer: 9/12 - 5/12 = 4/12 = 1/3
Step-by-step explanation: Like fractions are the fractions that have same denominators.
In order to find a pair of fractions whose difference is , we can use the concept of equivalent fractions as well.
We can have many many pairs of like fraction whose difference is . An example illustrated below will give a better understanding:
Here, 9/12 and 5/12 are like fraction. Their difference is 1/3

Answer:
V = 20.2969 mm^3 @ t = 10
r = 1.692 mm @ t = 10
Step-by-step explanation:
The solution to the first order ordinary differential equation:
Using Euler's method
Where initial droplet volume is:
Hence, the iterative solution will be as next:
- i = 1, ti = 0, Vi = 65.45
- i = 2, ti = 0.5, Vi = 63.88
- i = 3, ti = 1, Vi = 62.33
We compute the next iterations in MATLAB (see attachment)
Volume @ t = 10 is = 20.2969
The droplet radius at t=10 mins
The average change of droplet radius with time is:
Δr/Δt =
The value of the evaporation rate is close the value of k = 0.08 mm/min
Hence, the results are accurate and consistent!
