Saturday morning there was only 2/3 of a box of cereal for breakfast. shelly and her sleepover friends are 5/6 of what was left. how much of the cereal box did they eat?

Okay so what you want to do is find the mcd or most common denomanater
to do that you want to list out the factors of 3 and 6. after you do that you should see the the mcd is 6. so now 6 is your new denamanater. so you keep 5/6 and for 2/3 you multiply the top and bottum by 2 so your new fraction is 4/6
so there isnt a correct answer to thing question
