Example 1:
Jane ran 100 meters in 15 seconds. How long did she take to run 1 meter?
Step 1: Think of the word problem as:
If 100 then 15. If 1 then how many?
Step 2: Write the proportional relationship:
Answer: She took 0.15 seconds
Example 2:
If of a tank can be filled in 2 minutes, how many minutes will it take to fill the whole tank?
Step 1: Think of the word problem as:
If then 2. If 1 then how many? (Whole tank is )
Step 2: Write the proportional relationship:
Inverse is the opposite of proportion

Indirect proportion is more famously known as Inverse Proportion. Inverse proportion is the exact opposite of Direct Proportion. Inverse Proportion -As one quantity increases other quantity decreases. An example problem: If 4 painters can paint a house in 6 days then how many days can 8 painters paint a house of the same size? To solve, use cross product 4 painters=6 days 8 painters=x 4x6=24 24/8=3 To paint the same house,8 painters need 3 days.
direct
The inverse of addition is subtraction.
There cannot be a "proportion of something": proportion is a relationship between two things, and how you solve it depends on whether they (or their transformations) are in direct proportion or inverse proportion.
direct proportion: y=kx inverse proportion: y=k/x
when both increaes its direct proportion and when one increase and othe decreases its inverse proportion.
Direct Proportion Inverse Proportion Direct square Proportion Inverse Square Proportion Hope it helps :)
Inverse is the opposite of proportion
Inverse proportion is a mathematical concept and has nothing whatsoever to do with religious concepts such as hell.
Set up a proportion equation.
