Question

Julie wrote the rate 108$ in 6 weeks as a unit rate.Find her mistake and correct it.

Answer 1

Unit rate has 1 in the denominator. $108 in 6 weeks has 6 weeks as the denominator, which isn't one of anything (unless we treat 6 weeks to be a unit). What Julie probably intended as the unit rate was $108/6 weeks = $18 / week.
