numer of 0's at the end is in accordance to the number of numbers behind the number you are writing 

Answer:

7000 + 1500 + 20 + 3 = 8523

Or

7 thousands + 15 hundreds + 2 tens + 3 ones = 8523

Step-by-step explanation:

Consider the provided information.

We need to write the expanded form using 15 hundreds.

15 hundreds is equal to 1500,

Subtract 1500 from 8523

8523-1500=7023

Write 7023 in expanded form.

7 thousands + 2 tens + 3 ones

Now add 15 Hundreds which we have subtracted.

7000 + 1500 + 20 + 3 = 8523

Or

7 thousands + 15 hundreds + 2 tens + 3 ones = 8523
