Percent means parts out of 100
x/100=x%
roosters=6
x=percent
6/15=x/100
2/5=x/100
times both sides by 100*5
200=5x
divide both sides by 5
40=x
answer is 40%

Answer:
3=11
Step-by-step explanation:
Start of by doing -2-1
-10/2 = rational number
-13.4 = rational number
sqrt 18 = irrational number
22.7(repeating) = rational number
the oddball is sqrt 18 :)
Simplifying
8(x + 3) + -2x
Reorder the terms:
8(3 + x) + -2x
(3 * 8 + x * 8) + -2x
(24 + 8x) + -2x
Combine like terms: 8x + -2x = 6x
24 + 6x
