If there are 24 blue marbles, how many red marbles are there?Answer: Since the ratio of red to blue marbles is 3:5 and there are 24 blue marbles. Let the number of red marbles be x. Then 3/5 = x/24. Solving this equation gives x = (3/5) * 24 = 14.4, which is not possible as the number of marbles must be a whole number. There seems to be an error in the question or calculation. If we assume that the ratio is 3:4 instead of 3:5, then solving 3/4 = x/24 gives x = 18. So, there is likely an error in the question.22. What is 3/4 of 20?Answer: To find 3/4 of 20, we multiply 20 by 3/4. 20 * (3/4) = 15.23.

Tom has 5 apples. He gives 2 apples to Jerry. How many apples does Tom have now?Answer: Tom had 5 apples and gave away 2. So he has 5 - 2 = 3 apples now. The answer is 3.27.

You can only open one box and look at one fruit. Which box should you open to determine the correct contents of all the boxes?Answer: Open the box labeled “apples and oranges”.
