So, first we must calculate 37/50 as a percentage. First -- we know that 60 is a factor of 100, so we multiply the denominator by 2 to give us 100 (100 is the maximum is a percentage (in this case)). We also multiple the numerator by 2 as "whatever you do to the denominator, you do to the numerator vice versus". This overall gives us 74/100 which is 74%. Therefore 37/50 is bigger than 73%. Hope this helped ;)
