Answer:
The composite numbers are: 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, and 50
Step-by-step explanation:
Here, we are to write the composite numbers between 10 and 50. To do this, we need to know the numbers which have factors other than 1 and itself between 10 and 50.
With this, we need also the concept of divisibility.
a. Numbers divisible by 2 between 10 and 50 are numbers ending in even numbers, which are: 12, 14, 16, 18, 22, 24, 26, 28, 32, 34, 36, 38, 42, 44, 46, 48
b. Numbers that are divisible by 3 between 10 and 50 - where the sum of all the digits is divisible 3. The numbers are: 15 ( 1 + 5 = 6, where 6 is divisible by 3), 21 (2 + 1 = 3, where 3 is divisible by 3), 27 (2 + 7 = 9, where 9 is divisible by 3), 33, and 39.
Therefore, the numbers divisible by 3 between 10 and 50 are 15, 21, 27, 33, and 39.
c. Numbers divisible by 5 between 10 and 50. They are 25, 35, and 45.
d. Numbers divisible by 10. They are 10, 20, 30, 40, and 50
Therefore, the composite numbers between 10 and 50 are:
12, 14, 16, 18, 22, 24, 26, 28, 32, 34, 36, 38, 42, 44, 46, 48
15, 21, 27, 33, and 39
25, 35, and 45
10, 20, 30, 40, and 50
