Karen is a dog groomer. Rottweilers take 20 minutes to groom, border collies take 10 minutes to groom, and chihuahuas take 45 minutes to groom because they ferociously resist. How many minutes will it take Karen to groom 6 Rottweilers, 9 border collies and 1 chihuahua?
Let's think: First find the total time Karen spending grooming Rottweilers: 20 minutes / Rottweiler * 6 Rottweilers = 120 minutes. Then find the total time she spends grooming border collies: 10 minutes / border collie * 9 border collies = 90 minutes. Then add the time spent grooming all three kinds of dogs to find her total grooming time: 120 minutes + 90 minutes + 45 minutes = 255 minutes.. The answer is: 255.

There are 5 green candies, 3 blue candies, and 4 red candies in a bag. If Violet randomly picks a candy from the bag, how likely is it that it's blue?
Let's think: The total of candies is 5 + 3 + 4 = 12 candies. The probability of a candy being blue is (3 / 12) * 100% = 25%.. The answer is: 25.

Lilly and Fiona are cleaning a room. Between them, it takes 8 hours to clean the room. A quarter of the time spent cleaning was by Lilly and Fiona was responsible for the rest of the cleaning. How long, in minutes, was Fiona cleaning?
Let's think: Lilly cleaned for 8 hours / 4 = 2 hours. This means that Fiona was cleaning for 8 hours total cleaning – 2 hours Lilly’s cleaning = 6 hours. So in minutes, Fiona was cleaning for 6 hours * 60 minutes in an hour = 360 minutes.. The answer is: 360.

There are 350 trees in the park, 70% of which are pine trees. How many are not pine trees?
Let's think:
There are 350 x 70 / 100 = 245 pine trees. Therefore, 350 - 245 = 105 trees are not pine trees.. The answer is: 105.
