Value Question

Question

In the number 439 how is the value of the 3 related to the value of the 9?

Answer 1

The digital number system is a positional number system.  That means that the position of the digit (value from 0 to 9) is different depending on where it appears in a number.

 

Therefore, we have units place, tens place, hundreds place ... and tenths place, hundredths place, etc.

 

In the number 439, the 9 occupies the units place and so is worth 9 units.

The 3 is in tens place and is worth 3 tens, or 30 units.

The 4 is in the hundreds place and is worth 4 hundreds, or 40 tens, or 400 units.

 

[p.s. you need to know this if you ever want any dollars and cents]

 

The value of the 3 is worth a little more than 3 times the value of the 9.

     In fact, it is 30/9 = 3 1/3 times as much.
