empirical formula

1. relative ratios of three element are :                           whole no. ratio of the three elements are:

element 1=1.5,                                                                      3

element 2 =1.7                                                                       3.4

element 3= 2                                                                           4

for finding the whole number ratios with  decimal places less than 5 we have to multiply it by 2 in other cases we round off the simple ratios,
