3.For integers that lie between 1 to 10 (excluding 10 itself),subtract the sum of all the prime numbers from the sum of all the composite numbers,find the difference. prime numbers for integers that lie between 1 to 10 (excluding 10 itself) are 2, 3, 5, 7 thus, the sum of all the prime numbers = 2 + 3 + 5 + 7 = 17 composite numbers for integers that lie between 1 to 10 (excluding 10 itself) are 4, 6, 8, 9 Thus, the sum of all the composite numbers = 4 + 6 + 8 + 9 = 27 therefore, the difference of the sum of all composite numbers minus the sum of all prime numbers = 27 - 17 = 10 (Ans.) Ans. The difference is 10. 4.The fourth multiple of is divided by the second multiple of 6.Find the quotient. The fourth multiple of 6 = 6 * 4 = 24 The second multiple of 6 = 6 * 2 = 12 Thus, the quotient = 24 / 12 = 2 (Ans.) 5.Jacky ate 35% of a watermelon.find the percentage of watermelon remaining. The percentage of watermelon remaining = 1 - 35% = 100% - 35% = 65% (Ans.) 6.The area of a school hall has increased by 23 % after re-construction.what percentage of the previous area is the new area? The area of the new area = 1 * (1 + 23%) = 123% Thus, the percentage of the previous area is the new area = 1 / (123%) = 81.3% (apprp.) (Ans.)
