Question

Two and a half cats catch 4 mice in three and a half days. How many mice will five and a half cats catch in 21 days?​

My teacher also sad that the answer should be from 90 to 100 mice.​

Answer 1

Answer:

Step-by-step explanation:

4 mice / (2.5 cats * 3.5 days) = 16/35 mice per cat day

5.5 cats x 21 days = 115.5 cat days

115.5 cat days *  ( 16/35 mice/(cat day) ) = 52.8 mice

Answer 2

21 is the answer and yes
