Calculation of the Total Number of Discs

To determine the total number of discs, we need to add up the number of discs that each person distributed.

- Dima distributed 2/3 of all the discs. - Zina distributed 5/10 (which is equivalent to 1/2) of all the discs. - Masha distributed 6 discs.

Let's calculate the total number of discs step by step:

1. Dima distributed 2/3 of all the discs. Let's represent the total number of discs as x. Therefore, Dima distributed 2/3 * x discs.

2. Zina distributed 1/2 of all the discs. Using the same representation, Zina distributed 1/2 * x discs.

3. Masha distributed 6 discs.

To find the total number of discs, we can add up the number of discs distributed by each person:

2/3 * x + 1/2 * x + 6 = x

Now, let's solve this equation to find the value of x.

To solve the equation, we can combine like terms:

5/6 * x + 6 = x

Next, we can isolate x on one side of the equation:

6 - 5/6 * x = x

To simplify the equation, we can multiply both sides by 6:

36 - 5x = 6x

Now, let's move all the terms with x to one side of the equation:

36 = 11x

Finally, we can solve for x by dividing both sides by 11:

x = 36 / 11

Therefore, the total number of discs is approximately 3.27.

However, since the number of discs cannot be a fraction, we need to round the result to the nearest whole number. Therefore, the total number of discs is 3.

So, there were a total of 3 discs.
