alexandr402 [8]

Answer:

<u>900</u> black and white copies are printed.

Step-by-step explanation:

Given:

For every 9 black and white copies printed there are 2 color copies printed.

If there are 200 color copies printed.

Now, to find the number of black and white copies are printed.

Let the number of black and white copies printed be x.

As given, for every 9 black and white copies printed there are 2 color copies printed.

So, 9 is equivalent to 2.

If there are 200 color copies printed.

Thus, x is equivalent to 200.

Now, to solve by using cross multiplication method:

\frac{9}{2} =\frac{x}{200}

<em>By cross multiplying we get:</em>

1800=2x

<em>Dividing both sides by 2 we get:</em>

900=x

x=900.

Therefore, 900 black and white copies are printed.
