There are many different paths to take but here is my take
15%:22.5%:48%: 74 3/4 Turn everything into a percent
15%:22.5%:48%: 7475% Turn into a decimal
.15: .22: .48: 74.75 Times by 100
15: 22 : 48: 7475 Covert into factors
5(3) : 2(11) : 3(2⁴): 5²(299) Relize there is no common factor...
15: 22 : 48: 7475 <------- Whole numbers
