Answer:
Unit Form:
- 3 hundreds, 0 tens, 0 ones
- 5 thousands, 0 hundreds, 0 tens, 0 ones
- 9 thousands, 0 hundreds, 0 tens, 0 ones
- 7 ten thousands, 0 thousands, 0 hundreds, 0 tens, 0 ones
Standard Form:
Explanation:
Here is how to write solutions to expressions in unit form:
Its important to note that unit form expands a standard form number into ones, tens, hundreds, and so on.
Take your first expression for example.
10 × 3 tens
Re-write this expression so that all terms are in standard form. The second term is 3 tens, which can be represented as thirty.
10 × 3 tens
10 × 30
Solve this expression. Multiply ten by thirty.
10 × 30
300
The expression is now represented in its simplest form. We can start to write it in unit form. Break up three hundred into its hundreds, tens, and ones.
300
3 hundreds, 00
3 hundreds, 0 tens, 0
3 hundreds, 0 tens, 0 ones
This shows that the solution to the first expression written in unit form is 3 hundreds, 0 tens, 0 ones.
We can continue to solve the following expressions in the same manner. Just in case you still need some help. Here is how you find the remaining three solutions in unit form.
Problem Two
5 hundreds × 10
500 × 10
5,000
5 thousands, 0 hundreds, 0 tens, 0 ones
Problem Three
9 ten thousands ÷ 10
90,000 ÷ 10
9,000
9 thousands, 0 hundreds, 0 tens, 0 ones
Problem Four
10 × 7 thousands
10 × 7,000
70,000
7 ten thousands, 0 thousands, 0 hundreds, 0 tens, 0 ones
Here's how to solve the second part of the problem:
This portion says we need to write the solution in standard form. It is important to remember that a number written in standard form will looks like an ordinary number, i.e. 76, 902, 474.
This means that under the category titled 'standard form' we must write the answer as the ordinary solution.
