Idon’t want the answer but how to do solve this problem and how to solve scale

Step-by-step explanation:

Scale Factor (SF)

The scale factor is the number you multiply the real by to get the model, it can also be used the other way, for instance if a map's SF was 1in=1ft (or times 12) every 2 inches on the map would be 24 inches (or 2 ft) in real life.

If the SF is lower than 1 (a decimal like .7 for instance) then the result will be smaller (for Real to Model)

for the first one, 80 times the SF will equal 25

80 * X = 25

^Here is it in equation form, X being the scale factor

isolate X (or find what x equals by getting it by itself)

divide each side by 80

X = 25/80

simplify or divide

X = 5/16 or x = 0.3125 (Both of these ca.

ab will be equal to
