Note that: "%" ; or "percent" means "out of 100" ; or "divided by 100" .

Method 1)
15/50 = ?/ 100 ;
Look at the denominators:
50 * (what value?) = 100 ? ; → "100 ÷ 50 = 2" ;
→ 50 * 2 = 100 ;
So: "15/50 = (15*2)/(50*2) = "30/100" ; which is "30%" .
___________________________________________
Method 2:
___________________________________________
"15/50" = (15÷5) / (50÷5) = 3/10 ;
3/10 = (3*10) / (10*10) = 30/100 ; which is: "30%" .
__________________________________________
Method 3: (slight variation of "Method 2" above):
___________________________________________
"15/50" = (15÷5) / (50÷5) = 3/10 ;
3/10 = 0.3 = 0.30 = (0.30 * 100) % = " 30% " .

James receives a pay increase of 100% per month and has a starting salary of $500.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let b represent the rate of pay increase and a represent the initial pay.
Let us assume that he had received 128000 after the 8 months. hence:
128000 = ab⁸ (1)
Also in the 10th month, he had received 512000, hence:
512000 = ab¹⁰ (2)
From the both equations:
a = 500, b = 2
rate of increase = 200% - 100% = 100%
James receives a pay increase of 100% per month and has a starting salary of $500.
