no multiple of 5 has a 4 in the ones place!
So 2 is the required factor.
Apologies for the mistake. You are correct, none of the multiples of 5 will have a 4 in the ones place, so the required factor must be 2.
To find the factor, we need to figure out which multiplication fact will have a product with a digit 4 in the ones place.
Let's look at each option:
0: Any product multiplied by 0 will have a 0 in the ones place, not 4. So, 0 cannot be the factor.
2: If we multiply 2 by an even number, the ones place will end in 4 (e.g., 2 * 6 = 12). However, if we multiply 2 by an odd number, the result will have a 2 in the ones place (e.g., 2 * 3 = 6). Therefore, 2 can be the factor, but it is not a guarantee.
5: Multiplying 5 by any number will always have a 5 in the ones place, not 4. So, 5 cannot be the factor.
10: Multiplying 10 by any number will always have a 0 in the ones place, not 4. So, 10 cannot be the factor.
Based on the options provided, the factor that must be one of the solutions is 2.
