    A whole number has a 3 in the tens place. If the value of the 3 in a new number is ten times the value of the 3 in the original number, what must be true?

    a. The 3 in the new number is in the ones place.

    b. The 3 in the new number is in the tens place.

    c. The 3 in the new number is in the hundreds place.

    d. The 3 in the new number is in the thousands place

    Answer:

    c. The 3 in the new number is in the hundreds place.

    Explanation:

    A whole number is simply a counting numbers and can have differing numbers of digits in it. Whole numbers can be seen as natural numbers as it begin from 1. Whole numbers are also positive integers and in this case we include 0.

    In a whole number each digit has a fixed position called its place. For example in the number 235, the digit 5 is at one's or unit's place, digit 3 is at ten's place and digit 2 is at hundred's place.

    In the question;

    X3Y - sentence 1

    X3P * 10 = X3PA - sentence 2

    Where the letters are unknown digits with known places.

    Obviously from sentence 2 we see that the digit 3 has moved from the tenth place to the hundredth place.
