$3 M n O_{2} + 4 A l \to 3 M n + 2 A l_{2} O_{3}$ $3MnO_2+4Al -> 3Mn+2Al_2O_3$

Explanation:

Since we have a multiple of $3$ $3$ oxygens on the right hand side we require a multiplier of $3$ $3$ on the left hand side.

If we have $3 M n O_{2}$ $3MnO_2$ on the left hand side, then that is a total of $3$ $3$ manganeses and $6$ $6$ oxygens, requiring $3 M n + 2 A l_{2} O_{3}$ $3Mn+2Al_2O_3$ on the right hand side.

Then we need $4$ $4$ aluminiums on the left hand side.

Hence the balanced form of the equation is:

$3 M n O_{2} + 4 A l \to 3 M n + 2 A l_{2} O_{3}$ $3MnO_2+4Al -> 3Mn+2Al_2O_3$
