Justin took photographs during a trip to the mountains. He used one roll of
color film and one roll of black-and-white film. He took 1/3 of the pictures in
color during a picnic with his family. If he took 36 pictures in all, how many
color pictures did he take during the picnic?

36 / 1.3 =27.69(round up) 28 color pictures
1/3 * 36 = 12.
