If 1 in 15 adults have cardiovascular disease, approximately what percentage is this?

Explanation:
The main idea is converting a ratio phrased as “1 in 15” into a percentage. Treat this as the fraction 1/15, which equals about 0.066666... When you convert a decimal to a percent, multiply by 100. So 0.066666... × 100 ≈ 6.666..., which rounds to about 6.7%. Therefore, 1 in 15 adults with cardiovascular disease is about 6.7%. For quick checks: 0.5% would be 1 in 200, and 3.3% is roughly 1 in 30, while 15% is about 1 in 6.7. The given ratio best matches 6.7%.
