If the amount of money you spend in total is 5/6, and you spend 2/5ths of that on jeans, then 2/5 of 5/6 is what you want to get. To get that, we simply multiply the two to get 10/30 or 1/3 by dividing both the numerator and denominator by 10
Adult tickets + kids tickets = 120$
Y represents kids tickets
Z represents adult tickets
Z = twice kids tickets = 2Y
In ecuation:
Z + Y = 120$
Replace Z with 2Y
2Y + Y = 120 $
3Y= 120 / divided by 3
Y = 40$
You know the cost for 1 kid ticket
40 : 4 = 10 kids tickets sold
Z = 2x 40= 80$ for adult tickets
80:8 = 10 adult tickets sold
