First off, 'percent' literally means 'per hundred,' so 12.5 'per hundred' = 
5x-27+7x-32+9x-8=180

Answer:
MO = 12
PR = 3
Step-by-step explanation:
The perimeter of a triangle is calculated by adding all side lengths up:
The perimeter of triangle MNO is given as 48
The perimeter of triangle PQR is given as 12
The ratio is 1/4 (simplified ratio of 12/48)
we can write the following equation using this information:
cross multiply fractions
12x = 4x + 8
subtract 4x from both sides
8x = 8
divide both sides by 8
x = 1
Now to find the measure of side lengths in question we replace x with 1
for MO = 12x
12*1 = 12
for PR = x + 2
1 + 2 = 3
