number of chicken wings bought = x
number of fishballs bought = y
total money = m
chicken wing = cw
fishball = fb
This means that : x (cw) = 4/5 m
This means that : 1 (cw) : 1 (fb) = 5 : 2 orThe cost of each chicken wing to the cost of each fishball is in the ratio of 5:2.
Find the ratio of the number of chicken wings to the number of fishballs Sally bought for the party.
The question is x : y = ?
x (cw) = 4/5 m ------> equation 1
So the cost of the fishballs is 1/5 of the money. This means y (fb) = 1/5 m -------> equation 2
Equation 1 divided by equation 2 will give you result :
-----> equation 3
From the question :
----> equation 4
Subs. equation 4 to equation 3 will give you the answer ^^
