How many liters of water should be added to 18 liters of a 14% bleach solution so that the resulting solution contains only 10% bleach?

0.72 liters

Step-by-step explanation:

First, to solve this problem, since the 18 liters contain just 14% bleach, we will find the amount of bleach solution;

14% of 18 liters  =    ×   18   =    = 2.52 liters

This means we only have  2.52 liters of bleach

To get the numbers of liters that must be added to 2.52 liters so that it becomes 10% bleach, we need to find 10% of the solution

10% of 18 liters =  × 18 =   = 1.8 liters

SO, we will just subtract the 10% from the 14% solution

That is;

2.52 liters -  1.8 liters  = 0.72 liters

Therefore 0.72 liters of water must be added to 18 liters of a  14% bleach solution so that the resulting solution is 10% bleach.

answer: the answer is 100 x 12,500, which is 1,250,000.

step-by-step explanation: emily solved for a part when she should have solved for the whole.  

875,000 should be the numerator of the equivalent ratio.  

70 x 12,500 is 875,000.
