The answer depends on what the tens digit is greater than, and what the ones digit does then.
There is an infinite number of values between 40 and 50, or between 4/10 and 5/10. Try 45 in the first case, and 9/20 in the second.
To round 1395 to the nearest 10, we look at the digit in the tens place, which is 9. Since 9 is greater than or equal to 5, we round up. Therefore, 1395 rounded to the nearest 10 is 1400.
To round 4198 to the nearest 10, we look at the digit in the tens place, which is 9. Since 9 is greater than or equal to 5, we round up. Therefore, 4198 rounded to the nearest 10 is 4200.
9 tens = 90. 4 fewer ones than tens = 9 - 4 = 5. Therefore the answer is 95.
4 = thousands 5 = hundreds 9 = tens 7 = ones
5, with 9 ones left over.

To express the number "2 hundreds, 5 ones, 9 tens, and 3 tenths" in standard form, you would write it as 259.3. This is because the number 2 represents the hundreds place, the number 5 represents the ones place, the number 9 represents the tens place, and the number 3 represents the tenths place. Therefore, the number can be written as 259.3.

5 thousands = 5000. 10 tens = 100. 3 hundreds=300. 9 ones = 9. That's 5000 + 400 + 9, which is 5409
To round 389 to the tens place, we look at the digit in the ones place, which is 9. Since 9 is greater than or equal to 5, we round up the tens place. Therefore, 389 rounded to the tens place is 390.
