Question

Arlo works at a paint store. A formula for a certain color calls for 3/5  L of green paint. Arlo wants to make 1/3  less paint than the formula creates.   How much green paint should Arlo use?   Express your answer as a fraction in simplest form.

Answer 1

if he wants to make 1/3 less then he wants to make 2/3 of the formula
so (F= formula)

if 3/5L = F

and you want to find how much L is in 2/3 then you take

3/5L (2/3) = F (2/3)

you get 6/18L = 2/3F which can be simplified as 1/3 L = 2/3 F
