Question

Megan has3/4 of a cup of powdered sugar. She sprinkles 9/10 of the cup of sugar on to a plate of brownies and sprinkles the rest on some lemon cookies. How much sugar does Megan sprinkle on the plate of brownies?

Answer 1

Megan sprinkled 27/40 of the powdered sugar on the brownies.
3/4 = .75
.75 / 10 = .075
.075 x 9 = .675
.675 = 675/1000
675/1000 = 27/40
