We see that we have 6 + 4=10 oxygen molecules on the RHS, so we will have 10/2 = 5 molecules on the LHS. The final balanced chemical equation is C_3H_8 + 5O_2 -> 3CO_2 + 4H_2O This is a perfect example of a combustion reaction because we have a carbon based compound reaction with oxygen gas to produce carbon dioxide and water. Hopefully this helps!
