Answer:
n = 125
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Number n is 25 less than 120% of itself. What is the value of n?
25 less than 120% of itself can be represented as: <u>1.2n - 25</u>
n = 1.2n - 25
<u>Step 2: Add Subtract 1.2 from both sides</u>
n - 1.2n = 1.2n - 25 - 1.2n
-0.2n = -25
<u>Step 3: Divide both sides by -0.2</u>
-0.2n / -0.2 = -25 / -0.2
<em>n = 125</em>

3/5*3/3 = 9/15
5/15 + 9/15 = 14/15
