14. Erika spent 3 of her allowance. Write an equivalent fraction for the amount she did NOT spend.

Answer 1

Erika spent 3/1 of her allowance. To find the fraction for the amount she did not spend, we need to subtract 3/1 from 1/1 (which represents her entire allowance):

1/1 - 3/1 = (1-3)/1 = -2/1

However, this fraction is not in its simplest form, because it has a negative numerator. To make it positive, we can flip the fraction over and change the sign:

-2/1 = -2 => 2/(-1) = -2/1

Now we have an equivalent fraction that represents the amount Erika did not spend: -2/1 or 2/(-1).
