Question

Which is odd one out? Explain how you know?

15,000 ones 1,500 tens 15 thousands 15,000 15 ten thousands

Answer 1

Given:

15,000 ones, 1,500 tens ,15 thousands, 15,000, 15 ten thousands.

To find:

The odd one out.

Solution:

First, we need to convert all the values in the standard form of a number.

`15000\text{ ones}=15000* 1`

`15000\text{ ones}=15000`

Similarly,

`1500\text{ tens}=1500* 10`

`=15000`

`15\text{ thousands}=15* 1000`

`=15000`

`15\text{ ten thousands}=15* 10000`

`=150000`

The standard form of all numbers is 15,000 except 15 ten thousands.

Therefore, the odd one out is 15 ten thousands.
