On the blueprint of a house, 25 millimeters represents 4 meters. The actual length of the living room is 9 meters. What is its length on the blueprint?
set up a proportion
(25 mm / 4 m) = (x mm / 9 m)
x = 56.25 mm
(25 mm / 4 m) = (x mm / 9 m)
x = 56.25 mm
You set these numbers up in a proportion, with a as the variable for length on the blueprint:
25/4=a/9
Cross-multiply: 25x9=4a
Divide by 4: a=56.25
The length on the blueprint is 56.25 mm.

25mm ~ 4m
25/4 = x/9
6.25 = x/9
x = 56.25
Answer: 56.25mm
25/4 = x/9
6.25 = x/9
x = 56.25
Answer: 56.25mm
25 mm represent 4 m
? mm represent 9m
4x=225
x=225/4
x=56.25mm
? mm represent 9m
4x=225
x=225/4
x=56.25mm
25 mm(9)/4=56.25 mm
25/4 = x/9
x = (9 * 25) / 4
x = 56.25 mm
x = (9 * 25) / 4
x = 56.25 mm
