9hrs on sleep
6hrs on school
1.6 hrs on job
2.4 hrs on homework
1.92 hrs on meals

= 23/4
= 5 3/4
= 5 9/12

Answer:
- absolute error: 0.4 kg
- relative error: 6.1%
Step-by-step explanation:
The absolute error is the difference between the estimate and the actual weight:
7.0 kg -6.6 kg = 0.4 kg . . . . absolute error
__
The relative error is the ratio of the absolute error to the actual weight:
(0.4 kg)/(6.6 kg) × 100% = 6.060606...% ≈ 6.1% . . . . relative error
2*A=2*1/2ap -- 2A/a=pa/a -- answer is 2A/a=P or P=2A/a
