If you spent 1/2 at the theater, and 1/4 at the arcade then you spent 3/4 of your money leaving you with 1/4 left. multiply the amount of money you have left ($17.50), by 4. You originally had $70. hope this helps!
Well... 2/4+1/4=3/4 Or in other words, You spent 3/4 of your money (Half from Theater and 1/4 from the Arcade) and you have 1/4 of your money now $17.50 is 1/4 of your money you had before you spent all the money. To find the answer, you will multiply $17.50×4, since in this situation, you had 4/4 of money. $17.50×4=$70.00 You had $70 before you spent your money Hope this helped :D
