All this question is trying to ask is to find 78% percent of the total number of student in the class.

So first convert 78 to decimal by dividing it by 100: $\frac{78}{100} = 0.78$

Next multiply that with the total number of students which is 35.

So, $0.78 * 35 = 27.3$

Now I don't think there can be a decimal here. The question must be wrong or the percentage might be incorrect. But, just for sake, we'll round it up so the final answer would be: $27$

The proportion would be: $273:10$
