Answer:

#1:3#

Explanation:

To find ratio of the two, weshould first convert them first to same units.

One hour is #60# minutes and as such #1/4# hour is #1/4xx60=15# minutes and #1 1/4# hours is #60+15=75# minutes.

Hence #25"minutes":1 1/4"hours"#

is #25"minutes":75"minutes"#

and as #75/25=3#, the ratio is #1:3#
