Selma went to the mall and spent 1/3 of her money. She then lost 1/2 of what she had left. She then had $5. How much money did Selma originally have?
I know the answer is 30 but how do I explain others how to figure it out easily?
between the spending and the loss, she only had 1/6 of her money left.
5 is 1/6 of what number?
