Step-by-step explanation:
Size of the Mural is 42 feet long and 16 feet.
The original painting is 10½ inches long and 4 inches wide.
On the length
Length of Painting: Length of Mural
10½ inches: 42 feet
1 inch : 42/10½ feet
1 inch : 4 feet

Width of Painting: Width of Mural
4 inch: 16 feet
1 inch : 16/4 feet
1 inch : 4 feet
The Scale of the Original Painting to the Mural is therefore:
1 inch : 4 feet
