What number am I

My tens digit is double my ones digit. I am less than 70 greater than 60?


How do u figure this out need help to explain how to get the answer..

  • 2nd grade -

    x + 20 x = 21 x

    60 < 21 x <70

    try x = 3

    63

  • 2nd grade -

    Alternatively

    "If I am less than 70 greater than 60? "

    then the possibles are 61, 61 ....69

    so the tens is always 6

    then if
    "My tens digit is double my ones digit."

    then the ones digit is 6/2=3

    thus the answer is 63.

  • 2nd grade -

    If the number is less than 70 and greater than 60, the tens digit has to be 6. Now, if the ones digit is half the tens digit, divide 6 in half. The answer is 63.

  • 2nd grade -

    same as the others 63

  • 2nd grade -

    53-35
