Answer: 4/10
Step-by-step explanation:
2/5 = ?/10 As the amount of pieces correspond to the denominator

2x2 = 4
x=8+sqrt-8/12, x=8-sqrt-8/12
I think...
Set up a proportion: 25/100 = 50/n where n = # of teens surveyed
Simplify fraction: 1/4 = 50/n
Cross multiply: n = 200
So 200 teens were surveyed.
