155.6 CM I divided 168 by 100 to find 1% then i got 1.68cm then I times that by 5 to find 5% which was 8.4cm. Finally I subtracted 168 and 8.4 to get 155.6 CM I hope that helped :)
It should be 1/8 because if she takes 1/2 and they eat 3/8 you make the denominator the same and you subtract it and get 1/2 I hope I broke it down so you can understand
