Question

You baked muffins for your class. A dog ate 12 of them. That was 3/10 of the muffins you had. How many did you start with?

Answer 1

40

Explanation:

Suppose at the starting, you had "x" muffins.

12=( 3/10 )x Now let's divide both sides by 3/10

12/ (3/10)=x

12×(10/3)=x

40=x

You originally had 40 muffins.
