Answer:
Therefore 975 is divisible by 3 and 5 but not by 6
Step-by-step explanation:
Divisibility Test of 3=Sum of digits should be divisible by 3
975-9+7+5=21
21 is divisible by 3(7*3)
therefore 975 is divisible by 3
Divisibility test of 6= should be divisible by both 2 and 3
Divisibility of 2= last digit should be even
975 is not divisible by 2
975 is divisible by 3
Hence 975 is not divisible by 6
Divisibility test of 5=Last digit should be 5 or 0
975 is divisible by 5(Since last digit is 5)
