For this case we can use the following rule of three:
$ 500 ---------> 100%
$ 400 ---------> x
Clearing x we have:
x = (400/500) * (100) = 80%
Therefore, the percentage of decrease in the rent is:
p = 100-x
p = 100-80
p = 80%
Answer:
a proportion can be used to calculate p is:
p = 100 - ((400/500) * (100))
You get 2m+m-3n which simplifies to 3m-3n
8- hundreds

Answer:
14 ounces
Step-by-step explanation:
16 ounces = 1 pound
Multiply the above equation by 7/8:
(7/8)(16 ounces) = (7/8)(1 pound)
14 ounces = 7/8 pound
