Answer 10

if you had 8.06 I would round up to 8.1 need 2 digits
if you had 0.34 it would be 0.34

Answer 11

first the prefix
centi- 1/100
milli -1/1000
kilo - 1000
metre - unit of 1
deca - 10

example kilometer = 1000 meter= 1000m
millimeter = 1/1000 of 1 meter = 0.001m

precise meaning how accurate you can get the measurement
