To determine whether Alex is correct, we need to verify if the equation 21 divided by 3 equals 7.
To do this, we can perform the division calculation ourselves. Divide 21 by 3:
21 รท 3 = 7
As we can see, the result of the division is indeed 7. Therefore, the equation 21 divided by 3 equals 7 is true. Therefore, Alex is incorrect in stating that the equation is not true.
