No. We claim that

and use algebra to prove the statement.
Let

. Multiply this by ten to get

. Subtract the initial equation to give

and divide by

to see that

. Substituting into the original equation gives

, proving the desired statement.
84 divided into sevenths could either be:
84 x (1/7) or simply 84/7
In the end, the answer would be 12.
The answers should be
