1.	2. Express each as the sum of three odd prime numbers.(a) 15O 53(c) 43
Answer» Answer: We need to express the given numbers as the sum of odd primes. The prime numbers between 1 and 50 are LISTED below: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47. So using the above any three odd primes we need to express as the sum of the given number. (a) 21 = 3 + 7 + 11 (b) 31 = 3 + 11 + 17 (c) 53 = 13 + 17 + 23 (d) 61 = 19 + 29 + 13

Answer:

We need to express the given numbers as the sum of odd primes. The prime numbers between 1 and 50 are LISTED below:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47.

So using the above any three odd primes we need to express as the sum of the given number.

(a) 21 = 3 + 7 + 11

(b) 31 = 3 + 11 + 17

(d) 61 = 19 + 29 + 13
