Mary is baking cookies for her school bake sale. For every 5 chocolate chip cookies she makes 2 oatmeal raisin cookies. If she keeps this ratio, and bakes 84 cookies total, what will be the ratio of chocolate chip cookies to oatmeal raisin cookies?
It will still be 5 to 2.
correct
Because
2+5=7
sum of ratio is 7
2/7x84=24
5/7x84=60
now
24:60
2:5 (Took 12 as common)
To solve this problem, we need to find the ratio of chocolate chip cookies to oatmeal raisin cookies that Mary will bake.
We are given that for every 5 chocolate chip cookies, Mary bakes 2 oatmeal raisin cookies. This means the ratio of chocolate chip cookies to oatmeal raisin cookies is 5:2.
Since we know that Mary will bake a total of 84 cookies, we can calculate the number of chocolate chip cookies by dividing 84 by the sum of the parts of the ratio (5+2), which is 7.
Number of chocolate chip cookies = (84 / 7) * 5 = 60
Similarly, we can calculate the number of oatmeal raisin cookies by dividing 84 by the sum of the parts of the ratio (5+2), which is 7.
Number of oatmeal raisin cookies = (84 / 7) * 2 = 24
Therefore, Mary will bake 60 chocolate chip cookies and 24 oatmeal raisin cookies, resulting in the ratio of 60:24, which simplifies to 5:2.
