Unit rate means one. So the best way to solve this is using a proportion over one. If there are 258 pencils in 3 purses 258/3 then how many are in one purses x/1. Cross multiply next.
258/3 * x/1. You get 3x and 258. To get the x alone, divide both sides by three. Your answer is 86 pencils in one purse.
I got 6 units^2. So the answer is the second choice. ab/2 = 3*4/2 = 6.
The answer is 1.5 months
explanation:
5/2 = 2.5
15/4 = 3.75
2.5 per month
3.75 per x months
x = (3.75×1)/2.5
x = 3.75/2.5
x = 3/2 = 1.5 months
