75/200 movie goers watching 3D were students. 37.5% were students
50/100 movie goers watching 2D were students. 50% were students.
I believe the answer is 1/2
I changed 3 1/2 to an improper fraction (7/2), then I had to find the reciprocal of 7, which is 1/7. I then multiplied 7/2 by 1/7 which gave me 7/14, which I reduced to 1/2.
Hope this answers your question.

- Circumference of a Circle Formula: C = πd
Step-by-step explanation:
<u>Step 1: Define</u>
Circumference <em>C </em>= 141.3 ft
<u>Step 2: Solve for </u><em><u>d</u></em>
- Substitute in <em>C</em> [Circumference Formula]: 141.3 ft = πd
- Substitute in π (approximation): 141.3 ft ≈ 3.14d
- [Division Property of Equality] Divide both sides by 3.14: 45 ft ≈ d
- Rewrite: d ≈ 45 ft
Combine like terms (5y and -y= 4y) and the simplest form would be 4y+7
