Question

Reeba is baking cookies for the bake sale. She bakes 3 ¾ dozen chocolate chip cookies to sell . If Reeba sells ⅔ of the cookies, how many cookies did she sell?

Answer 1

30 cookies

Explanation:

Reeba sells
`(2)/(3)` of
`3(3)/(4)` of 12 chocolate chip cookies.

Let us start by finding
`3(3)/(4)` of 12. We simply have to multiply the two numbers. However, it would be much easier if we had an improper fraction than a mixed number. Let us make
`3(3)/(4)` an improper fraction first.

`3(3)/(4) =(15)/(4)`

Ok! Let's multiply.

`(15)/(4) *(12)/(1) =\\15*3\\=45`

Ok, Reeba baked 45 cookies in total. We know that she sells
`(2)/(3)` of her baked cookies, so we can again multiply the two numbers.

`(2)/(3) *(45)/(1) =\\2*15=\\30`

Therefore, Reeba sold 30 cookies.

I hope this helps! Let me know if you have any questions :)
