And please explain also ​

Answer 1

Step-by-step explanation:

538 + 234 + 4,318 = 5090

Rough Estimate by rounding off to nearest hundred is :- 5000

For Closer estimate :-

538 rounding off to nearest 10 = 540

234 rounding off to nearest 10 = 230

4,318 rounding off to nearest 10 = 4310

Adding 540 + 230 + 4310 = 5080 (closer estimate)
