Answer:

1050

Step-by-step explanation:

We can use a ratio to solve

First find how many jam

210 - 189 =21

We want to find how many jam for 10500 printed

21 jam x jam

----------- = ----------------

210 printed 10500 printed

Using cross products

21 * 10500 = 210x

Divide each side by 210

21*10500/210 =x

1050=x

Let’s take the number .666666 repeating

If we turn it into a fraction it’s 2/3.

It doesn’t matter how many numbers repeat to write a fraction.

Hope this helps.
