Respuesta :

Answer:

D) 471, 473, 475, 477, 479

Step-by-step explanation:

Lets say the three-digit number is ABC.

4 in the hundreds place, thus A = 4

7 in the tens place, thus B = 7.

The number is odd, therefore C = {1, 3, 5, 7, 9}

There are five possible solutions for three-digit number ABC = {471, 473, 475, 477, 479}
