Correct Answer
C. 3Explanation
The highest common factor (HCF) of 9, 15, and 24 is 3. To find the HCF, we can list the factors of each number and find the largest factor that is common to all three numbers. The factors of 9 are 1, 3, and 9. The factors of 15 are 1, 3, 5, and 15. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The largest factor that is common to all three numbers is 3, so the HCF is 3.Rate this question:

Find The LCM of 20, 24, and 30.
- A.
120
- B.
40
- C.
60
- D.
74
Correct Answer
A. 120Explanation
The LCM (Least Common Multiple) is the smallest number that is divisible by all the given numbers without leaving any remainder. To find the LCM of 20, 24, and 30, we can start by finding the prime factorization of each number. The prime factorization of 20 is 2 x 2 x 5, 24 is 2 x 2 x 2 x 3, and 30 is 2 x 3 x 5. Then, we take the highest power of each prime factor that appears in any of the numbers, which gives us 2^3 x 3^1 x 5^1. Multiplying these together, we get 120, which is the LCM of 20, 24, and 30.Rate this question:

Find The sum of 695 and 455 and then divide the result by the difference between 39 and 34.
- A.
245
- B.
230
- C.
259
- D.
247
Correct Answer
B. 230Explanation
To find the sum of 695 and 455, we add the two numbers together: 695 + 455 = 1150.
Next, we find the difference between 39 and 34: 39 - 34 = 5.
Finally, we divide the sum (1150) by the difference (5): 1150 / 5 = 230.
Therefore, the correct answer is 230.Rate this question:

- A.
4 1/3
- B.
3 ½
- C.
5 1/3
- D.
4 ½
Correct Answer
B. 3 ½Explanation
To find the product of the mixed numbers 1 ½ and 2 1/3, you can follow these steps:
1. Convert the mixed numbers into improper fractions:
1 ½ = 3/2
2 1/3 = 7/3
2. Multiply the two improper fractions:
(3/2) * (7/3) = (3 * 7) / (2 * 3) = 21/6
3. Simplify the resulting fraction:
21/6 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3:
(21 ÷ 3) / (6 ÷ 3) = 7/2
So, the product of 1 ½ and 2 1/3 as a mixed fraction is 3 1/2.Rate this question:
