Hey there!

QUESTION:

“15 is what percentage of 30?”

SIDE NOTE(S):

We will label “x” as the unknown number until we find what the actual number is.

⚠️Remember⚠️

PERCENTAGES RUNS OUT OF 100

SOLVING YOUR QUESTION:

15 = x% of 30

x% of 30 = 15

x% * 30 = 15

x/100 * 30 = 15

3/10 * x = 15

x * 3/10 = 15

MULTIPLY 10/3 to BOTH SIDES

x * 3/10 * 10/3 = 15 * 10/3

CANCEL out: 3/10 * 10/3 because it gives you 1

KEEP: 15 * 10/3 because it helps solve for the x-value (to find out what the actual percentage number is)

NEW EQUATION: x = 10/3 * 15

SIMPLIFY IT!

x = 50

ANSWER:

Therefore, your answer should be about [50%]

Good luck on your assignment and enjoy your day!
