Question

(a) (e) 6 is a multiple of 18 True or false of both 18 and 24 Find a number that is a factor (m) Find a prime number and a multiple of 4 that when added together give another prime number. Write down the first five multiples of 9

Answer 1

(a) False. 6 is not a multiple of 18.(e) The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The common factors of 18 and 24 are 1, 2, 3, and 6.(i) A number that is a factor of both 18 and 24 is 6.(m) A prime number is a number that has only two distinct positive divisors: 1 and itself. A multiple of 4 is a number that can be divided by 4 without leaving a remainder. One example of a prime number that is a multiple of 4 is 2. When 2 is added to another prime number, such as 3, the result is 5, which is also a prime number.Write down the first five multiples of 9: 9, 18, 27, 36, 45.
