Answer 1

Answer:

composite number

1 , 3 , 5 , 7 & 9   ( only odd digits)

Step-by-step explanation:

A number line between 50 and 70, has its one's digit as 2. Is it composite or prime?

As number lies between 50 & 70

so ten's digit can not be two

so unit digit must have to be two

this will be an even number so composite number

Either 52 or 62

52 = 2 * 26  = 4 * 13

62 = 2 * 31

composite number

For a two digit number to be prime, what may be the possible digits at one's place?​

1 , 3 , 5 , 7 & 9   ( only odd digits)
