Question

What percent of 4 hours is 8 seconds?

Answer 1

So 4 hours
1 hour=60 minutes
1 minute=60 seconds
1 hour=60 times 60 seconds=3600seconds
4 hours=3600 seconds times 4=14400seconds

so 8 out of 14400
8/14400=2/3600=1/1800
percent means parts out of100 so
x%=x/100
the reatios are equal to
1/1800=x/100
mulitply both sides by 100
100/1800=x
1/18=x
divide out
0.055555555=x
round
0.06%
