Question

I have 30 marbles and I have 8 blue marbles. What is the percent of the blue marbles?

Answer 1

You can write a statement like, what percent of 30 is 8 and form an equation:
x= 8*100/30 = 800/30 = approx. 26.6
 Concluding that 8 is approx 26.6% of 30

Answer 2

Hey there! :)

Blue: 8
Total: 30

Blue to total: 8/30 = 8 ÷ 30

Divide

8 ÷ 30 = 0.2666 = 0.27

0.27 = 27%

Your answer is 27%

Rounded to the nearest tenth: 26.6%
Rounded to the nearest whole: 27%

Hope this helps :)
