Question

In the number 37,781, how are the values of the two 7s related to each other?

Answer 1

In a number each place value is 10x more than the value to its right:

 

      3       +          7         +       7        +    8    +    1

________      ____________  ___________  ______  _____

     Ten       Thousands  Hundreds  Tens   Ones

Thousands

 

The number 37,781 consists of:

 

3  ten thousands (10⁴) +

7  thousands  (10³) +

7  hundreds  (10²) +

8  tens  (10¹) +

1  one  (10⁰)

 

Thus the 7 thousands are 10x more than the 7 hundreds.
