How's life ppl?

Anyways,

now i will be talking about Direct and Inverse Proportion.

Does it sound complicated?

Yup, I think so too -.-

Ok, here goes:

Proportion basically means a statement of quality between two ratios.

i) Direct proportion.

Definition: When a relation between two variables remains constant, they are said to be in direct proportion.

Example question:

John reads three pages of a book every ten minutes.

The ratio " Pages over Time " is constant.

Therefore,

3 pages over 10 minutes

= 6 pages over 20 minutes

= 9 pages over 30 minutes

= 12 pages over 40 minutes

=...................

and it goes on and on and on n on n on...........


ZZZZZZZ

ii) Indirect (or inverse) proportion.

Definition: When one variable is multiplied by a number and the other variable is divided by the same number, they are said to be in indirect proportion.

Example question :

It takes four hours for one person to mow the lawn.

It takes two hours for two people to mow the lawn.

So, the result will be something like this:

1 person = 4 hours to mow lawn

2 people = 2 hours to mow lawn.

3 people = 1 1/3 hours to mow lawn

4 people = 1 hour to mow lawn

8 people = 1/2 hour to mow lawn.

And that's all!
