URGENT URGENT URGENT How would i calculate the percentage increase of my science experiment?

the resting heartrate was 80bpm (beats per minute) and after excersise it was 155bpm which is a difference of 75.



How would i figure out the percentage increase?



Your help is muchly appreciated :)URGENT URGENT URGENT How would i calculate the percentage increase of my science experiment?
80bpm = 100%

74 = x%



(75 * 100)/80 = (75 * 5)/4 =93.75%



Hope that helpedURGENT URGENT URGENT How would i calculate the percentage increase of my science experiment?
155/80 X 100 =193.75, so it saw a 194% increase, depending on how you're supposed to round sig figs.



think about it like new rate /old rate = x/100, because something over 100 is a percent, and 155/80 is like the increase ratio.



OR think about it like (percent increase X original rate = new rate), so x/100 X 80 = 155. same answer, things are just moved around a bit.



best of luckURGENT URGENT URGENT How would i calculate the percentage increase of my science experiment?
75/80*100 = 93.75% increase, which means ur new hearbeat was 193.75% of ur old hearbeat.
