Tina and Joey share a 18-ounce box of cereal. By the end of the week, Tina has eaten 1 6 of the box, and Joey has eaten 2 3 of the box of cereal. How many ounces are left in the box?

Answer:The number of ounces of cereals left in the box is 3

Step-by-step explanation:

Tina and Joey share a 18-ounce box of cereal. By the end of the week, Tina has eaten 1/6 of the box. This means that the amount of cereal that Tina ate is

1/6 * 18 = 3 ounce

Also, by the end of the week, Joey has eaten 2 / 3 of the box of cereal. This that the amount of cereal that Joey ate is

2/3 * 18 = 12 ounce

The number of ounces of cereals left in the box would be

18 - (12 + 3) = 18 - 15

= 3
