give the compound a mass of 100 grams, so that the mass of each element is
C=52.14% of 100g = 52.14g
H=13.13g
O=34.73g

convert the mass to moles
divide the mole value by the smallest number of moles calculated
round to nearest whole number, this is the mole ratio / subscripts

C=52.14% of 100g = 52.14g
H=13.13g
O=34.73g
