peevee say: 5 cm = 2 inches; 10 cm = 4 inches.
2 inches = 5 cm; 1 inch = 2.5 cm; 25 inches = 2.5 x 25 cm
2.5 x 25 = 62.5 cm.
10 cm = 4 inches and 25 cm = 62.5 cm.

moe say: Given; 2 in = 5 cm or 5 cm = 2 in
if 5cm = 2 in then
10cm = 2*(10/5) in = 4 in <- ans1
if 2 in = 5 cm then
25 in = 5*25/2 = 62.5cm <- ans2

Paul say: If 2 inches = 5 cm then 4 inches = 10 cm note you just multiply both sides by 2.
Now to turn 2 inches into 25 inches just multiply both sides of the equation by 25/2
2 * 25/2 inches = 5 * 25/2 cm
25 inches = 62.5cm

derfram say: Easiest way to is set it up as a ratio:
2 in/5 cm = x in/10 cm; solve by cross multiplying:
5x = 20
x = 4 in
2 in/5 cm = 25 in/x cm
125 = 2x
x = 62.5 cm
