We have to explain that 1 hundred 4 tens and 14 tens name the same amount.
Consider 1 hundred 4 tens
Since, 1 hundred = 100
It can also be expressed as " 100 = 10 tens"
So, 1 hundred = 10 tens
Now, 1 hundred 4 tens = 1 hundred + 4 tens
= 10 tens + 4 tens
= 14 tens
=
![14 * 10](https://img.qammunity.org/2019/formulas/mathematics/middle-school/4evje3yk7c6e791u5lqjgtf4zkqaubtb0f.png)
= 140
Consider 14 tens
=
![14 * 10](https://img.qammunity.org/2019/formulas/mathematics/middle-school/4evje3yk7c6e791u5lqjgtf4zkqaubtb0f.png)
= 140
Therefore, 1 hundred 4 tens and 14 tens represents 140, so it represents the same amount.
