I have just started a uni course, already I am struggling in this weeks work which is fractions, decimals & percentages. My main problem is I dont know the process in how to work the problems out.
Three children camping out & go to sleep with a pack of marshmallows unopened in their ten. ONe child wakes up & eats 1/4 of the marshmallows & then goes back to sleep. A short time later another child wakes up & eats 1/3 of the remaining marshmallows & then goes back to sleep. Later in the night the other child wakes up & eats half of the remaining marshmallows & then goes back to sleep. When they all awak in the morning there is only 9 marshmallows left, How many marshmallows were in the pack at the start of the night?
Do I start by converting the fractions into %, all I know is 9 is my starting point.
