It is 5000.
10 times 2/5
21.5 in expanded form = (2 x 10) + (1 x 1) + (5/10)
Hundreds.
To round off 321 to the nearest 10, you would first identify the digit in the tens place, which is 2. Since the digit in the ones place is less than 5, you would round down to the nearest 10. Therefore, 321 rounded to the nearest 10 is 320.

It is 5000.
10 times 2/5
21.5 in expanded form = (2 x 10) + (1 x 1) + (5/10)
50 (nearly 51). But the fifty hundreds are in the form of 5 thousands: no left-over hundreds as such.
We expand 715 into 7 hundreds, 1 ten, and 5 ones. This can be written as 7(100) + 1(10) + 5(1) = 715.
500 in standard form is 5.0 x 102
Hundreds.
Every coin, if the measurement unit is chosen appropriately/
The standard form of 27 thousands, 3 hundreds, and 5 ones is 27,305. In standard form, we write the number using commas to separate groups of three digits, starting from the right. In this case, we have 27 thousands, 3 hundreds, and 5 ones, which combine to form the number 27,305.
To round off 321 to the nearest 10, you would first identify the digit in the tens place, which is 2. Since the digit in the ones place is less than 5, you would round down to the nearest 10. Therefore, 321 rounded to the nearest 10 is 320.
