The two angles are x and 9x/5
<h3 /><h3 />
Let the two angles we require be x and y.
<h3 /><h3>Ratio of both angles</h3>
We have that the ratio of both angles are x:y
Since both angles are in the ratio 5:9, we have that,
x:y = 5:9
⇒ x/y = 5/9
<h3 /><h3>Value of the other angle</h3>
So, we Make y subject of the formula
Multiplying both sides by y, we have
y × x/y = 5/9 × y
x = 5y/9
Multiplying both sides by 9, we have
9 × x = 5y/9 × 9
9x = 5y
Dividing both sides by 5, we have
9x/5 = 5y/5
y = 9x/5
So, the two angles are x and 9x/5

Example A means
For every #of felt pieces you multiply that by the cost of one piece of felt to see how much you spent
Example
Felts cost $3 a piece
You get 7 pieces
7 x 3= 21
You spent $21 on felt
Step-by-step explanation:
56,000÷7=8000
56,000÷70=800
56,000÷700=80
56,000÷7000=8
The answer is the bottom right one:
12/40 x 100
