3 1/3hrs : 45
Changing 3 1/3 from mixed number to improper fraction
3 1/3 = 10/3 hr
To divide the two numbers in the ratio they must hv the same units (ie min )
Hence changing 10/3 hr to min
=10/3 x60 = 200 min

Ratio
= 200/45
Since there is a common factor which is 5 divide through by 5
=40/9
= 40 : 9
Answer = 40:9
