100/1200= x/100
cross multiply
(1200 * x)= (100 * 100)
1200x= 10000
divide both sides by 1200
x= 8.333% winning chance
LOSING CHANCE
100% - 8.333%= 91.667%
RATIO OF WINNING TO LOSING
100 tickets= winning chance
1200 total - 100= 1100 losing chance
100:1100
simplify by 100
1:11 odds of winning to losing
ANSWER: The chance of winning is 8.333% and the chance of losing is 91.667% or 1:11.
Hope this helps! :)

Step-by-step explanation:
wish i could see the diagram to help
<span>Unknown factors = is also known as a factor that is
not understood and not known.
Example of unknown factor
=> 3x + 1 + 2
=> 3 + 3x
=> this is called unknown because we don’t have any idea what’s the value of
x
Quotient => An answer of 2 different numbers called dividend and divisor
being divided with each other.
Example of quotient
=> 100 / 10 = 10
=> 100 = dividend
=> 10 = divisor
= 10 = quotient

Answer:
A unit rate is the price per object.
For example, lets say each apple costs $2. The unit rate is 42 per apple.
THe fraction is:
X
----------
2X + 5
Decreases the numerator and denominator by 1, the fraction becomes 3/8.
So now the fraction looks like this:
X-1 3
--------- = -----------
2x +5-1 8
Cross multiplies:
8(x-1) = 3 ( 2x +5 -1)
8x - 8 = 3( 2x + 4)
8x - 8 = 6x + 12 <--- distributive right side
8x - 8 - 6x - 12 = 0 <--- everybody moves left,changing signs, to keep leading coefficient of x term positive
2x - 20 = 0 <-- combines like terms
2x = 20 <--- solves for x
x=10
So the fraction 10/25.
(10-1)/(25-1) = 9/24 = 3/8
