Answer:
1 inch : 4 feet
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
On the Width
Width of Painting: Width of Mural
4 inch: 16 feet
1 inch : 16/4 feet
1 inch : 4 feet

1) $375
500 *.25= 125
500-125= 375
2) (5/8)* 32= 20 girls in class
(3/8)* 32= 12 BOYS in class
4) 19+42+X=87
62+X= 87 (add 19 and 42 together )
X=25 ( subtract 87 from 62)
