Answer:

$\frac{3}{10}$ of his allowance doesn’t go into Dion’s savings.

Step-by-step explanation:

We know that $\frac{7}{10}$ of Dion’s savings is going into his savings.

Since the denominator is “10” we know that $\frac{10}{10}$ is the fraction that represents all of his allowance money.

So, we would subtract $\frac{7}{10}$ from $\frac{10}{10}$ .

$\frac{10}{10}$ - $\frac{7}{10}$ = $\frac{3}{10}$
