Answer:
I would go with the first one.
Step-by-step explanation:
The first one is the only one that increases by the same number. In other words, its slope is constant. A linear function has a constant slope. You can tell that it increases by 1/2 every time.
The answer is: [C]: "30%" .

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% " .

Exact form 27/4
decimal form 6.75
mixed number form 6(3/4)
20^2 + 21^2 = 27^2
400 + 441 = 729
881 = 729 (does not equal)
