Find out how many heartbeats in 1 second. 16 / 12 = ?

OpenStudy (anonymous):

Divide 16 / 12. Then, multiply that to 60.

OpenStudy (igreen):

Sorry, that's 12 / 16, not 16 / 12.

OpenStudy (anonymous):

Oh yeah :p

OpenStudy (anonymous):

This is direct proportion,If the heart beats 12 times in 16 sec,it will beat more than 12 times in 60 sec. You cross multiply @Rainbow_dashie
