Question 1086603: Mary counted 15 cupcakes left from the whole batch that Mother made for the picnic. "We've already eaten two-fifths," she shouted. How many cupcakes did Mother bake. I tried 15* 2/5 and came up with 6 eaten from the 15. I then added 6 to the 15 showing that 21 cupcakes were made. However, that seems to tell me that the two-fifths made be in error. I know that the unknown is the total amount of the cupcakes baked. Unclear as to how to find the unknown with a problem as 15 X 2/5=x or 15 + 2/5x=x. Thank you.
