You must set up an equation for this problem. Your equation is 10=0.2x. If we divide both sides by 0.2, we get 10/0.2=x which equals x=50. This means your number is 50 because 0.2*50=10.
She can serve 26 guests (because 19 1/2 divided by 3/4 is 26) and no ice cream will be left (because 26 is a whole number).
