To solve this question all we have to do is divide 77 by 0.55
Why 0.55 because 0.55 is the decimal version of 55%
once we divide 77 by 0.55 that will give us our answer of 140 cookies.
Now to check our answer:
If Joel made 140 cookies and 77 of those cookies are chocolate chip that would leave us with 63 cookies without chocolate chips. If we estimate our answer then 63 cookies would make total sense since we know that 55% = 77
then the other 45% would have to equal around 60-70 cookies
