Question

Refer to the picture below, sorry for constant questions, btw.

Answer 1

1 inch : 5 yards.

Explanation:

Paco's first scale was 2 : 5 which is 1 : 2.5.

Now as the length of the pool on the drawing was reduced from 10 in to 5 ins, that means the scale was doubled so the answer is:

1 : 2*2.5 = 1 : 5 .
