Question

So there was this question and it was if Gina can complete 2/3 on a braclet In 3/4 hours what is her rate for making brackets. The answer is 8/9. But now what is her unit rate in brackets per hour. Also how many hours does it take to make 1 braclet. Please help me

Answer 1

2/3 in 3/4 of an hour

(2/3)/(3/4) = (2/3)(4/3) = (2)(4)/(3)(3) = 8/9 of a bracelet in one hour

one bracelet = (2/3)(3/2) bracelet in (3/4)(3/2) = 9/8 hours= 1 1/8 = 1.125 hours
