**Hint:**Take the digits and use the rule to round the numbers to the nearest tens:

1) If the ones digit is $5$ or more than 5 then the tens digit is increased by $1$.

2) If the ones digit is $4$ or less than 4 then the ten digit stays the same.

**Complete step-by-step answer:**

Rule to round the numbers to the nearest tens:

1) If the ones digit is $5$ or more then tens digit is increased by $1$.

2) If the ones digit is $4$ or less the tens digit stays the same.

So for $28$ the nearest tens is $30$ because 8 is greater than 5 so tens number 2 is increased by 1.

For $32$ the nearest tens is $30$ because 2 is less than 4 so tens number 3 remains the same.

For $52$ the nearest tens is $50$ because 2 is less than 4 so tens number 5 remains the same.

For $41$ the nearest tens is $40$ because 1 is less than 4 so tens number 4 remains the same.

For $39$ the nearest tens is $40$ because 9 is greater than 5 so tens number 3 is increased by 1.

For $48$ the nearest tens is $50$ because 8 is greater than 5 so tens number 4 is increased by 1.

For $64$ the nearest tens is $60$ because 4 is at ones place so tens number 6 remains the same.

For $59$ the nearest tens is $60$ because 9 is greater than 5 so tens number 5 is increased by 1.

For $99$ the nearest tens is $100$ because 9 is greater than 5 so tens number 9 is increased by 1.

For $215$ the nearest tens is $220$ because 5 is at ones place so tens number 1 is increased by 1.

For $1453$ the nearest tens is $1450$ because 3 is less than 4 so tens number 5 remains the same.

For $2936$ the nearest tens is $2940$ because 6 is greater than 5 so tens number 3 is increased by 1.

**Note:**This general rule of estimation tells you to look at the digit to the right of the digit you want to estimate, and if it is less than $5$ then you round down, and if it is greater than $5$, you round up.

Students generally get confused between the place values of numbers like tens place hundreds place and sometimes make mistakes while we get 5 as a number which is right to the place we are rounding off.
