Answer:
Step-by-step explanation:
If ¼ of a box is filled with candies and the rest is cookies, then the fraction of cookies in the box will be expressed as;
fraction of cookies in the box = 1 -¼
fraction of cookies in the box = [tex]\frac{4-1}{4}[/tex] [tex]= \frac{3}{4}[/tex]
If 3/5 of the cookies are chocolate chip cookies, then the amount of chocolate chip cookies in the box will be 3/5 of 3/4 i.e 9/20 chocolate chip cookies. If the rest are oatmeal raisin cookies, the amount of oatmeal raisin cookies will be 3/4 - 9/20
fraction of oatmeal raisin cookies = 3/4 - 9/20
= (15-9)/20
= 6/20
= 3/10
Hence 3/10 of the box is an oatmeal raisin cookies
