Hi uncle john :D may i know how to remove the 5 from 5n. Thank you
n must be = 3*11 so that
(5*3*11) can be divided by (3*11).
if n is not equal to 3*11 then 5n cannot be divided by 3*11. if that is the case 30n cannot be divided by b.
The question said 30n is a multiple of b means it can be divided by b. From there we derive that n is equal to 3*11.
