10, 20, 30.... Any even multiple of five.
Any multiple of 10.
A multiple of 10 must end in a zero
If a number is a multiple of 5, it will be greater than 5 and end in a 5 or a zero.
yes because if it has a zero or five at the end you know its a multiple of 5
If it has a 0 or a 5 at the end of it.
They always end in either five or zero.
Yes. All multiples of 5 end in 0 or 5. 75 ends in 5 so it is a multiple of 5. 75 = 15 x 5.
Any number that does not end with 0 or 5 is not a multiple of 5
no multiples of 5 only end in 0 or 5 so 8,521 ends in 1 so is not a multiple of 5
10, 20, 30, 40, 50...
Every other number that ends in 5 is a multiple of 5 this is why
no such number. a mutliple of 5 has to end in 5 or 0 which you have listed both as not to use
