Question

Q.8 What is the tail length?

Answer 1

If I'm correct you should make a fraction first
5.4            3.6
-----    to    -----
4.8              ?

Now find the missing number
5.4 to 3.6 would be a difference of ÷ 1.5 so you must do the same for 4.8
     
           ÷1.5   
5.4               3.6
-----       to    -----
4.8                3.2
           ÷1.5

The tail length should be 3.2 feet
