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
