Jenny bought 2 bags of carrots for her 6 rabbits. In the 2 bags of carrots, there are 52 carrots. How many carrots will each rabbit get if Jenny divides them equally for her 6 rabbits? Alfred wrote the expression: 52 ÷ 2. Is Alfred correct? Explain why or why not.

Given the ratio for dinosaur stamps to airplane stamp, the correct ratio is 18 : 12

How to find ratio

Dinosaur stamps = 18

Airplane stamps = 12

John wrote:

ratio of dinosaur stamps to airplane stamps = 12 to 18

Correct ratio:

ratio of dinosaur stamps to airplane stamps = 18 : 12

= 18/12

= 3/2

= 3 : 2

  • Bags of carrots = 2
  • Number of carrots in both bags = 52
  • Number of rabbits = 6

Number of carrots per rabbits = 52 ÷ 6

= 8.67 carrots per rabbits.

Therefore, Jenny's expression is correct.
