Here are the solutions for questions 14-30 from the image, with special attention to questions 14 and 16. 14. 5/8 of a class are boys. What fraction are girls? Step 1: The total fraction representing the class is 1. Step 2: Subtract the fraction of boys from the total. Fraction of girls = 1 - (5)/(8) = (8)/(8) - (5)/(8) = (3)/(8) The final answer is a) (3)/(8). 15. Add (3)/(8) + (4)/(7) Step 1: Find a common denominator for 8 and 7, which is 56. (3)/(8) = (3 × 7)/(8 × 7) = (21)/(56) (4)/(7) = (4 × 8)/(7 × 8) = (32)/(56) Step 2: Add the fractions. (21)/(56) + (32)/(56) = (21+32)/(56) = (53)/(56) The calculated answer is (53)/(56). This result is not among the given options. The final answer is (53)/(56). 16. 7/8 of candidate who wrote an entrance exams passed and the rest fail. What fraction of candidates fail? Step 1: The total fraction of candidates is 1. Step 2: Subtract the fraction of candidates who passed from the total. Fraction failed = 1 - (7)/(8) = (8)/(8) - (7)/(8) = (1)/(8) The calculated answer is (1)/(8). This result is not among the given options. The final answer is (1)/(8). 17. Multiply 484 by 12 Step 1: Perform the multiplication. 484 × 12 = 5808 The final answer is b) 5808. 18. Divide 63 by 3 Step 1: Perform the division. (63)/(3) = 21 The calculated answer is 21. This result is not among the given options. The final answer is 21. 19. 40 peoples are to be shared equally among 10 prison inmate. How many can each inmate get? Step 1: Divide the total number of people by the number of inmates. (40)/(10) = 4 The calculated answer is 4. This result is not among the given options. The final answer is 4. 20. Compare: 28 + 11 \_ 16 + 4 Step 1: Calculate both sides of the comparison. 28 + 11 = 39 16 + 4 = 20 Step 2: Compare the results. 39 > 20 The final answer is a) >. 21. Compare: 33 + 11 \_ 70 + 4 Step 1: Calculate both sides of the comparison. 33 + 11 = 44 70 + 4 = 74 Step 2: Compare the results. 44 < 74 The final answer is b) <. 22. Compare: 60 + 10 \_ 30 + 5 Step 1: Calculate both sides of the comparison. 60 + 10 = 70 30 + 5 = 35 Step 2: Compare the results. 70 > 35 The final answer is a) >. 23. Change (2)/(100) to decimal fraction Step 1: Divide the numerator by the denominator. (2)/(100) = 0.02 The final answer is c) 0.02. 24. Convert (3)/(5) to percentage Step 1: Multiply the fraction by 100%. (3)/(5) × 100\% = (300)/(5)\% = 60\% The final answer is c) 60\%. 25. What is the value of 5 in 785002 Step 1: Identify the place value of the digit 5 in the number 785002. The digit 5 is in the thousands place. Step 2: Calculate the value. 5 × 1,000 = 5,000 The final answer is c) 5000. 26. Add 2536 to 456 Step 1: Perform the addition. 2536 + 456 = 2992 The final answer is b) 2992. 27. Subtract 456 from 2536 Step 1: Perform the subtraction. 2536 - 456 = 2080 The final answer is b) 2080. 28. Triangle which has two side equal is called .... An isosceles triangle has at least two sides of equal length. The final answer is d) Isosceles triangle. 29. An angle which measured 90^ is called.... An angle that measures exactly 90^ is called a right angle. The final answer is c) Right angle. 30. Square has all the side equal A square is a quadrilateral with four equal sides and four right angles. The statement is true. The final answer is a) True. Got more? Send 'em!
