X = the amount of water to add
10 - x = amount of 18% bleach to add
.18(10-x)= .12 x 10
1.8 -.18x =1.2
-.18x = -.6
x = 3 1/3 liters water
therefore 6 2/3 liters bleach
The number is 84. If you find numbers that equal 12 that are both one digit numbers, you have 9 and 3, 8 and 4, and 7 and 5. If you put 48, together they equal 12. If you divide 84 by 7, you will get 12. 84 reversed is 48, which is 4 times 12. So if you times 84 by 4/7, you will get 48.

Answer:
30 gallons
Step-by-step explanation:
Let c represent the capacity of the container. Then we have ...
2/5c + 8 = 2/3c
Multiplying by 15 clears the fractions:
6c +120 = 10c
120 = 4c . . . . . . . . subtract 6c
30 = c . . . . . . . . . . divide by 4
The container can hold 30 gallons.

<em>Additional comment</em>
Often, you are told to "clear fractions" first when solving equations that involve them. Here, you can work directly with the fractions, if you like.
8 = (2/3c) -(2/5c) = 4/15c . . . . . find the difference of the fractions
8(15/4) = c = 30 . . . . . . . . . . . . . multiply by its inverse
