A baseline record lists waist 82 cm and hip 100 cm. Calculate waist-to-hip ratio as waist / hip to two decimals; do not classify risk.
- A1.22
- B0.80
- C0.45
- D0.82
Show answer and explanations
Answer
D
82 / 100 = 0.82. This is a ratio, not a diagnosis.
A
100 ÷ 82 = 1.22: hip was divided by waist, the reverse of the specified ratio.
B
82 ÷ 100 = 0.8200; rounding to one decimal (0.80) ignores the two-decimal instruction.
C
82 ÷ (82 + 100) = 0.45: waist was divided by the sum of both circumferences.
D
82 / 100 = 0.82. This is a ratio, not a diagnosis.
