For every 9 black and white copies printed there are 2 color copies printed. If there are 200 color copies printed how many black and white copies are printed?

900 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

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, is equivalent to 200.

Now, to solve by using cross multiplication method:

By cross multiplying we get:

Dividing both sides by 2 we get:

Therefore, 900 black and white copies are printed.

There were 900 black and white copies printed.

Step-by-step explanation:

Given:

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

2 color copies  = 9 black and white copies

We need to find the number of black and white copies if there are 200 color copies.

solution:

First we will find the number of black and white copies for 1 color copy.

Now we know that;

2 color copies  = 9 black and white copies

1 color copy = Number of black and white copies for 1 color copy.

By Using Unitary method we get;

Number of black and white copies for 1 color copy =

Now we can say that;

1 color copy = 4.5 black and white copy

200 color copies =  Number of black and white copies for 200 color copy

Again By Using Unitary method we get;

Number of black and white copies for 200 color copy =

Hence There were 900 black and white copies printed.

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
