Explanation:
________________________________________________________
Set up a proportion; as a fraction; as follows:
________________________________________________________
400/ 25 = x / 8 ;
in which: "x" = the number of "ounces [oz.] there are in "8 lbs." ;
________________________________________________________
We shall solve for "x" , the answer to the problem:
Cross-factor multiply:
25x = (400) * 8 ;
→ 25x = 3200 ;
Divide each side of the equation by "25" ; to isolate "x" on one side of the equation; & to solve for "x" ;
→ 25x / 25 = 3200 / 25 ;
→ x = 128 .

Answer: " 128 oz. " .
_________________________________________________________
There are: " 128 oz. " (in " 8 lbs." ) .
_________________________________________________________
Note of interest: " 16 oz. = 1 lb. " (exact conversion).
So; "8 lbs. <span>= ?</span> oz. " ;
→ " 8 lbs. * (16 oz/ 1 lb) = ( 8 * 16) oz. = 128 oz. ; → which is our answer!

Percent change = (new number - old number)/(old number) * 100
If the percent change is positive, it is a percent increase.
If the percent change is negative, it is a percent decrease.
In our case, the number goes from 500000 (the old number) to 60000 (the new number).
percent change = (new number - old number)/(old number) * 100
percent change = (60000 - 500000)/(500000) * 100
percent change = -88%
Answer: the percent decrease is 88%
Answer:
40 7th Graders
Step-by-step explanation:
First you add all of the students to get 25. Then you divide 100 by 25 to get 4 (this is gonna be your multiplier) now multiply each part of the ration by 4, and you get 60 6th graders and 40 7th graders :D.
