7×3/2×2×2+24 is your answer.
You just go backwards. For example, instead of 1/2 you would flip it and do times 2.
Am I making sense or do you need me to explain more?
Kerri's father bill was a baker. Out of his usual morning batch of cookies bill burned the first 2 dozen cookies. He gave half of what was left to Keri to take to school. He wrapped up half of the remaining cookies and have them to a group of fireman. He gave two thirds of what was left to the policeman. If bill had only 7 cookies left, how many cookies were in the original batch?

It makes sense thank you!
[(x-24)/2 ] after Keri
[(x-24)/4 ] after firemen
[(x-24)/4 ] (1/3) after policeman
= 7
so
[(x-24)/4 ] = 21
(x-24) = 84
x = 108
================
================
check
(108 - 24 /4 = 21
* 1/3 = 7 sure enough
