Question

Show that 25 is not a factor of 245​

Answer 1

Step-by-step explanation:

factor divides a number such that the remainder left behind is zero (0). When we divide 245 by 25, we see that the remainder becomes zero but the answer is in decimal ie 9.8 and the quotient must not be in decimal if it has to be a factor of the dividend. Thus 25 is not a factor of 245.
