The number 0.127 is how much greater than 1/8 ?
can you explain this so i can understand how it works?

It's 0.002 bigger. for each number to the right you go from 10th 100th 1000th. So 0.127 is .002 thousandth much bigger. so 0 would be the unit the 1 would be the tenth the 2 would be the hundredth and the 7 is the thousandth the same goes with 1/8. you would put 1/8 in a calculator and get 0.125 so you can see the difference

.  

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
