Answer:
87.0%
Step-by-step explanation:
If we rewrite what is given we get that 3450 out of the 3966 students are taking math. Putting this into a fraction we get that:
[tex]\frac{Students-taking-math}{total-amount-of-students} = \frac{3450}{3966}[/tex]
Putting this in a basic calculator of any kind we find that this is equal to:
0.8698941
This is the fraction as a number, so to get it as a percentage we just have to multiply by 100%:
0.8698941 · 100% = 86.98941% ≈ 87.0%
