Which of kirks grandparents have a higher chance of listening to heavy metal?

Hey there!

All you have to do for this problem is calculate the percentage of metal albums out of the total amount of albums for each grandparent. Whichever grandparent's ratio is higher will be your answer of which grandparent is more likely. 

You can figure out the ratio by dividing the smaller number by the larger number:

Maude: 135 / 225 = 0.6 or 60% of her albums are metal
Claude: 270 / 450 = 0.6 or 60% of his albums are metal

Since both of their music collections are 60% metal albums, I would say that they both have the same chance of picking a metal album to listen to, based on the information that was given in this problem. 

Hope this helped you out! :-)

You can divide the smaller number by the greater number to get your ratio.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
