Write an addition exercise in the format of hundreds + tens + units to make the number shown below:
To solve the problem of representing the number using hundreds, tens, and units, follow these steps:
The hundreds digit is 4, which represents .
There is no digit shown for the tens place, which means it is 0, representing .
The units digit is 7, which represents .
Adding these together, we have:
.
Therefore, the number 407 can be represented as the sum , since the tens place contributes nothing.
The correct choice that matches this representation is:
What number do the blue squares below represent?
An empty place value means there's no digit there, so it contributes zero to the total. In 407, the tens place is empty, so we have 0 tens.
Because the 4 is in the hundreds place, not the tens place! Look at the column headers - the 4 sits under 'Hundreds', making it worth 400, not 40.
In the final addition, you can skip writing since it doesn't change the sum. So 400 + 7 is the simplified form of 400 + 0 + 7.

Then you'd add all three values! For example, if you had 4 in hundreds, 3 in tens, and 7 in units, it would be .
