Answer:
value/total value • 100 = percentage
Explanation:
if 5 out 100 kids have red backpacks then 5% of kids have red backpacks
5/100 • 100 = percentage
0.05 • 100 = percentage
5% = percentage
if 13 cars out of 41 have flat tires, then 32% of the cars have flat tires
13/41 • 100 = percentage
0.31707317073... • 100 = 31.707317073... %
depending on your precision, you may include as many decimal places as you like, unless the question specifies it. For our example, we will round to 2 decimal places.
31.707317073... % = 31.71%
if you're looking to find percentages for probability, you will use the same equation.
the odds of flipping a coin and it landing on heads are 50%
possibilities:
Heads, Tails
there is one outcome where our result occurs out of the two possible outcomes
1/2 • 100 = percentage
0.5 • 100 = percentage
50% = percentage
Hope this helps and wasn't confusing
