1 to 90
It's not difficult:
75 feet = 75x12 = 900 inches real airplane
10 inches toy airplane
900/10 = 90

If the real plane is 75 ft long, you convert that into inches first (multiply by 12). 75 x 12 = 900 in. Since the toy one is 10 inches, the scale is 900 / 10 = 90

actual plane : 75 feet * 12 inches / feet = 900 inches
toy plane: 10 inches
10 : 900 divided by 10
1 : 90
means 1 inch in the toy plane is 90 inches in the actual plane.

I agree, 1 to 90.
75 feet x 12 inches = 900 inches.
10 inches / 900 inches = 1 to 90.

1/90...but that's kind of an odd scale...most mass-produced models in that range are 1/72 or 1/120. Whatever.

75 feet = 12 * 75 = 900
900/10 = 90
1in. : 90in.
or
1in : 7.5ft
