Answer:

She should sell <u>66</u> band posters.

Step-by-step explanation:

Given:

A collector has 135 movie posters and 90 band posters.

The collector wants to sell 36 movie posters.

But still want her collection to be the same ratio of 135:90.

If she sells 36 movie posters.

Now, to find the band posters she should sell.

Her current ratio of movie posters to band posters is 135:90.

If she sells 36 movie posters, she will have left.

135-36\\\\=99\ posters.

As, she wants the ratio to be maintain same.

So, let the number of the band posters she should sell be x.

<em>If, 135 is equivalent to 90.</em>

<em>Thus, 99 is equivalent to </em>x.<em />

Now, to solve using cross multiplication method:

\frac{135}{90} =\frac{99}{x}

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

<em />135x=8910<em />

<em>Dividing both sides by 135 we get:</em>

<em />x=66.<em />

<u><em>The number of the band posters she should sell = 66.</em></u>

Therefore, she should sell 66 band posters.
