To convert 2.6 hours into seconds which two ratios could you multiply by?

One hour is composed of 60 minutes and each minute has 60 seconds. Hence,
                     1 hr x (60 min / 1 hr) x (60 s/ 1 hr) = 3600 seconds
Each hour has 3600 seconds. To convert the given,
                    2.6 hours x (3600 s/ 1 hr) = 9360 seconds
Therefore, 2.6 hours is also equal to 9360 seconds.
