A 12 ounce bottle of shampoo last enrique 16 weeks.how lonh would you expect an 18 ounce bottle of the same brand to last him?

tankabanditka [31]

For Enrique a 12 ounce bottle lasts for 16 weeks. This is a known fact. We need to find the amount of days or weeks an 18 ounce bottle of the same brand of shampoo last.
Now
12 ounce bottle lasts = 16 weeks
   = (16 * 7) days
   = 112 days
18 ounce bottle lasts = (112/12) * 18
      = 168 days
   = 168/7 weeks
   = 24 weeks
So 18 ounce of the same brand of shampoo will last for 24 weeks.

Find Z for the following proportion

krek1111 [17]

This is the simplest proportion i have seen.
This is how we do it:
$\frac{z}{7}$ = $\frac{1}{7}$
The answer surprisingly is obvious, z = 1
But we can still do cross multiplication

7z = 7
Divide by 7 to isolate z

$\frac{7z}{7} = \frac{7}{7}$
7 and 7 cancels out
z = 1
