Let's write it down:
<span>"60 is 75% of s" means:
60=75%*s
75% is

, (percent just means "out of 100" so we just divide it by 100) so we can also write:
60=</span><span>

s
now, let's multiply both sides by 4:
240=3s
and divide by 3:
80=s
So we have the result that the original value, s, is 80!

Answer:
3347000 cm is 33.47 km to cm
3347000/64=
401.92 is the circumference
since it is pi * d
do 3347000/401.92
8327.52786624 round to
8327 full revolutions
The second one is the correct answer
