The total capacity of 6 pitchers and 12 glasses is 21 liters. The capacity of a pitchers if 5 times that of a glass. Find the capacity of each glass in liters.

let x = glass capacity

6(5x) + 12x = 21

Solve for x.

Let's solve this problem step by step.

First, let's assume the capacity of a glass is "x" liters.

According to the given information, the capacity of a pitcher is five times that of a glass. Therefore, the capacity of a pitcher is 5x liters.

Now, let's calculate the total capacity of all the pitchers and glasses.

Since there are 6 pitchers, the total capacity of the pitchers is 6 times the capacity of a pitcher, which is 6 * 5x = 30x liters.

Similarly, since there are 12 glasses, the total capacity of the glasses is 12 times the capacity of a glass, which is 12 * x = 12x liters.

According to the problem statement, the total capacity of all the pitchers and glasses is 21 liters. Therefore, we can write the equation:

Total capacity of pitchers + Total capacity of glasses = 21 liters

Substituting the values we found earlier, the equation becomes:

30x + 12x = 21

Simplifying the equation:

42x = 21

Now, divide both sides of the equation by 42 to solve for x:

x = 21 / 42
x = 0.5

Therefore, the capacity of each glass is 0.5 liters.
