How many meters is it? A. 0.5 meters.B. 5 meters.C. 50 meters. Answer: A. A centimeter is one hundredth of ameter. So 50 centimeters is 50/100 = 0.5 meters.17. 1 kilometer is equal to how many meters? A. 10 meters. B. 100 meters. C. 1000 meters. Answer: C. 1 kilometer is equal to 1000 meters.18.

A box contains red and blue marbles in the ratio of 3:5. 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. If a class has 30 students and 2/5 of them are girls, how many boys are there?Answer: First find the number of girls. 2/5 of 30 is (2/5) * 30 = 12. So the number of boys is 30 - 12 = 18.24. The ratio of apples to oranges in a basket is 4:3. If there are 12 oranges, how many apples are there?Answer: Since the ratio of apples to oranges is 4:3 and there are 12 oranges. Let the number of apples be x. Then 4/3 = x/12. Solving this equation gives x = (4/3) * 12 = 16.25. What is the fraction equivalent of 0.6?Answer: 0.6 is equal to 6/10 which simplifies to 3/5.26. 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. There are 10 pencils in a box. If 3 pencils are taken out, how many pencils are left in the box?Answer: There were 10 pencils and 3 were taken out. So 10 - 3 = 7 pencils are left. The answer is 7.28. Mary has 8 books. She buys 4 more books. How many books does she have in total?Answer: Mary had 8 books and bought 4 more. So 8 + 4 = 12 booksin total. The answer is 12.29. There are 12 students in a class. 6 students are boys. How many students are girls?Answer: There are 12 students in total and 6 are boys. So 12 - 6 = 6 students are girls. The answer is 6.30. A bag has 7 red balls and 3 blue balls. How many balls are there in total?Answer: There are 7 red balls and 3 blue balls. So 7 + 3 = 10 balls in total. The answer is 10.31. What is the result of rotating a square 90 degrees clockwise?Answer: The square will still be a square but with different orientation. Rotating a square 90 degrees clockwise changes its position but not its shape.32.

Enlarginga circle by a scale factor changes its size.35. If a pentagon is rotated 180 degrees counterclockwise, what is the result?Answer: The pentagon will be in a different orientation but still a pentagon. Rotation changes the position of the shape.36. There are three boxes, one contains only apples, one contains only oranges, and one contains both apples and oranges. The labels on the boxes are all wrong. 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”. If you find an apple inside, then this box must contain only apples. Since the labels are all wrong, the box labeled “oranges” must contain both apples and oranges, and the box labeled “apples” must contain only oranges. If you find an orange inside, the reasoning is similar.!.37. Tom is taller than Jerry. Jerry is shorter than Lucy. Lucy is shorter than Lily. Who is the shortest?Answer: Jerry is the shortest. Tom is taller than Jerry. Jerry is shorter than Lucy and Lucy is shorter than Lily.!.38. In a group of three people, A, B, and C. A is taller than B. C is shorter than B.
