Ken spent 1/5 of his allowance on a movie, 3/8 on snakes, and 2/7 on games. If of his allowance was $20, how much did Jen have left

Respuesta :

20 X 0.2(1/5 in decimal form) = 4

20 X 0.375(3/8 in decimal form) = 7.50

 20 X 0.285714285714(2/7 in decimal form) = 5.71

4 + 7.50 + 5.71 = 17.21

he had $2.71 left
