Why i calculate is 1.3 not 1.5

[@samrusoff]

Why does he say that (3/8) / (2/7) is "excellent, perfect" when it's the incorrect RR? I'm doubtful of this presentation, he seems to ask question of the audience just to assert dominance.

[@EccentricAuntWanda1]

I agree that this is incorrect and too bad he missed it. Regarding asking the audience - this is a typical part of resident training.

[@salimvohra]

Agree with ​​⁠@EccentricAuntWanda1, the mistake happened because it’s not a normal 2 x 2 tablespoons as it should have the ‘Had a headache’ ‘No column and then the ‘Total’ column, the questions I’m assuming is because he’s assuming they’ve either covered it as homework or in a previous class.
