Answer:
The estimated quotient is equal to 3
Explanation:
Remember that when you say nearest ten you reffer to rounding up or rounding down to the near multiple of 10.
1. Estimate the nearest ten for the divisor

As the number 25.98 is greater than 25 you must round up to the next ten that is 30.
2. Estimate the nearest ten for the dividend:
Note that if I add "4 zero decimals" to number 5 (5.0000), and then compare with 5.0299 it’s evident that 5.0299 is greater than 5.

As the number is greater than 5 you round it up for the next ten number which is 10.
3. Perform the mathematical operation diving 30 by 10:
=30 ÷ 10 = 3
4. The estimated quotient is equal to 3
