Answer:
[tex]\frac{3}{10}[/tex] of his allowance doesn’t go into Dion’s savings.
Step-by-step explanation:
We know that [tex]\frac{7}{10}[/tex] of Dion’s savings is going into his savings.
Since the denominator is “10” we know that [tex]\frac{10}{10}[/tex] is the fraction that represents all of his allowance money.
So, we would subtract [tex]\frac{7}{10}[/tex] from [tex]\frac{10}{10}[/tex].
[tex]\frac{10}{10}[/tex] - [tex]\frac{7}{10}[/tex] = [tex]\frac{3}{10}[/tex]
