Question

2 cheng has 2 pails of fish. each pail has the same number of fish. which could be the number of fish that cheng has in all? circle all the correct answers. a 5 b 9 c 10 d 13 e 18

Explanation:

Step1: Understand the problem

Cheng has 2 pails with the same number of fish, so total fish = 2 × (number of fish per pail). Thus, total fish must be even (divisible by 2).

Step2: Check each option

• A. 5: \(5\div2 = 2.5\) (not integer, so no)
• B. 9: \(9\div2 = 4.5\) (not integer, so no)
• C. 10: \(10\div2 = 5\) (integer, so yes)
• D. 13: \(13\div2 = 6.5\) (not integer, so no)
• E. 18: \(18\div2 = 9\) (integer, so yes)

Answer:

C. 10, E. 18
