Answer:
<u>1/6</u>
Step-by-step explanation:
<u>P (red)</u>
- No. of red / Total
- 3 / 3 + 4 + 2
- 3/9
- 1/3
<u>P (green without replacing red)</u>
- No. of green / Total - 1
- 4 / 9 - 1
- 4/8
- 1/2
<u>P (final)</u>
- P (red) × P (green without replacing red)
- 1/3 × 1/2
- <u>1/6</u>
What it wants you to do is to put it into a form where on the one side of the equation there is y and nothing else. for this, we need to get rid of the 0.9.
how do we do that?
we divide both sides of the equation by 0.9:
6.3/0.9=y
that's ugly, right? but if both denominator and nominator are decimal fractions of the same sort; we can multiply both by 10 and get rid of the point:
63/09=y
and...

so basically 7=y, or y=7
and this is the solution!
