Formula used: An equation that equates two rates of ratios is called proportions. Therefore, if b≠q and d≠q, then: ab=cd is a proportion. Calculation: As it is provided that Tim takes his pulse for 10 seconds and counts 12 beats. Let x represent the number of beats in one minute or sixty seconds. Set up a proportion by writing two equivalent ratios: 12 beats10 seconds=x beats60 seconds Multiply by LCD, that is 60. 60×12 beats10 seconds=x beats60 seconds×60 12(6)=x Solve the resulting linear equation, x=12×6 x=72 Thus, the rate of beats is 72 beats/min.
