Question

To convert 2.7 hours into seconds, which two ratios could you multiply by?

Answer 1

2.7 hrs x 60 (for minutes) = amount of minutes
amount of minutes x 60 (for seconds) = amount of seconds.

IN this case

2.7 x 60 = 162 minutes

162 x 60 = 9720 seconds.

so the two rations are 1:60 or (hr: min) then 1:60 or (min: seconds)

hope this helps :D
