A barista averages making 16 coffees per hour. At this rate, how many hours will it take until she's made 1,200 coffees?

Sagot :

75 hours
1200 coffees/16 coffees= 75 hours
apologiabiology
16 times x=1200 or 
16x=1200
divide both sides by 16
1200/16
so we  simplify 1200/16 by factoring out the ones (4/8=1/2 times 4/4 since 4/4=1)
1200=3*2*2*2*2*5*5
16=2*2*2*2*1
so we notice that there are four 2's in both so those are the 'ones' so cross them off and get
3*5*5/1 or 75/1 or 75 hours
