<span>It is not clear whether the populations are proportional to the radii or to the areas, but I seem they are proportional to the areas, which is to say to the square of the radii. So China's population % should be (17%)(3.4/3.2)^2 = sorry I don't bring a calculator right now. But you can solve it easily.</span>
Answer:
30 is the correct answer because 3times 10 =30 5 times 6 is 30 and 10 times3 is also 30
1 is expressed in decimal simply as 1.00
23/100 is expressed in decimal by 0.23
1 is a whole number and for it to become a decimal we must convert it into a fraction and perform division. 1 in fraction form is simply 1/1 which equals to 1.
23/100 to become decimal we need to divide 23 by 100. It will give us a quotient of 0.23
Add 3 to 72... so 3 plus 72 is 75
X=75
