/12 /1

7.41 11.12
/7.41 /7.41

1 : 1.5
becuase empirical formula is the simplest whole number fraction the empirical formular is 2:3 ( C2H3)

Answer 2

Divide 88.88 by 12 for the carbon, and (100 - 88.88) by 1 for the hydrogen.

Then turn those numbers into an empirical formula by dividing the larger one by the smaller.
