Answer:
The number of Oatmeal cookies at the party were:
15
Explanation:
It is given that:
The total number of cookies at the school party were: 40 cookies
Also the ratio of chocolate cookies to Oatmeal cookies are: 5: 3
So, let the number of chocolate cookies= 5x
and the number of Oatmeal cookies= 3x
Hence, we have:
5x+3x=40
( since number of chocolate and oatmeal cookies is equal to the total number of cookies)
i.e.
8x=40
on dividing both side of the equation by 8 we have:
x=5
Hence, Number of chocolate cookies= 5×5=25 cookies.
and Number of Oatmeal cookies= 5×3= 15 cookies.
