Is one out of ten the same as a 1 whole number?

No, one out of ten is not the same as a whole number. by saying you have 1 whole thing you are saying it is not divided in any way.. therefore it is whole. if you say you have one tenth of something or 1/10 you are saying you have one piece out of those ten that was once all one bigger whole piece combine, you are saying what was once one is now that one divided up even smaller pieces and if they are smaller they are not the same or equal

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
