Ed has 4 9/10 cups of powdered sugar. He sprinkles 1/3 of the sugar onto a plate of brownies and sprinkles the rest onto a plate of lemon cookies. How much sugar does Ed sprinkle on the brownies?
Answer provided by our tutors
4 9/10 = (4*10 + 9)/10 = 49/10
(1/3)*(49/10) = 49/30 = 1 19/30
Ed sprinkles 1 19/30 cups of powdered sugar on the brownies.
