"35% of his time" translates into 0.35 times 8 hours. What's that?

What are the units of measurement? Your answer's not complete without them.

Please show your math: 0.35 times 8 hours.

  • mathmale
Use a calculator if you wish. Or multiply by hand:\[\frac{ 35 }{ 100 }*8\]

Jessica, you were correct to begin with. What are the proper units of measurement?
mathmale
  • mathmale
Yes, this person spent 2.8 .... what? .... on roller coasters.

What you have here is 168 min or 2 hours and 20 min. Because if you multiply 0.35 by 8 than you will get 2.8 which means that there were two hours and 20 min.

2.8 time on the roller coaster?
mathmale
  • mathmale
2.8 hours. J-Chic: Try again. 0.8 hours is equivalent to more than 20 minutes.
anonymous
  • anonymous
he spent 2 hours and 80 minutes so you must make your minute less than 60 (because there is only 60 minutes in a hour not 80)

Sorry I typed that wrong
mathmale

Hippo: No. You mean that this person spent 2.8 hours, which means 2 hours plus 0.8 hour, NOT 80 minutes. Fix this, please. How many minutes in 0.8 hour?
jchick
  • jchick
The first part was correct on mine because I said 168 min. This translates to 2.8 hours.
jchick
  • jchick
Now 2.8 hours equals 48 min
mathmale
  • mathmale
True, but normally we'd say "2 hours, xxx minutes." How many min. in 0.8 hour?
jchick
  • jchick
Sorry 2 hours and 48 min
mathmale
  • mathmale
Gotcha.

Yeah I realized I had made a mistake lol I don't know why I wrote 20 min the first time.
