In solving Indirect Proportion, you must group the terms of the given ratios according to the given groups. Then, do the cross multiplication, then division. Then after that, do the reciprocal of the [tex] \frac{x}{n} [/tex] ratio.
Example:
My family hired 7 workers to finish our house for [tex]2 \frac{1}{2} [/tex] month. How many days will be our house built if we hired 11 workers?
Solution:
WORKERS - DAYS
7 [tex]n[/tex]
11 45 (days equal to [tex]2 \frac{1}{2} [/tex] month)
= Approximately 28 days
