Question

test the divisibility of number by 6a 7020 b 73510​

Answer 1

Answer:

for a number to be divisible by 6

i) it must be divisible by 2 that is , even

ii) it must be divisible by 3

(a) 7020

=> it's even ,so divisible by 2

=> sum of each number = (7+0+2+0 = 9) ,that is , it is divisible by 3

so , 7020 is divisible by 6

(b) 73510

=> it's even, so divisible by 2

=> sum of each number= (7+3+5+1+0 = 16) hence not divisible by 3

.so 73510 is NOT divisible by 6
