With a proportion set up to equal like this, you would cross multiply 21*500 which will equal 10,500. Then take 10,500 and divide it by 100 which will give you 105. 105 out of 500 is your answer equal to 21 out of 100.

Answer:

105

Step-by-step explanation:

500 goes into 100, 5 times

21 times 5 is 105

So 21/100 is equal to 105/500

Or you can do

500*0.21=105
