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

Answer: The number to the left of AC should be 6.

Explanation: The balanced chemical reaction is one in which the number of atoms of each element on the reactant side must be equal to the number of atoms on product side.

The given equation $A_2B + DC_3 \rightarrow AC + D_2B_3$ is unbalanced as the atoms on the reactant side are not same as number of atoms on product side. This equation is called as skeletal equation.
