Question

Give a rough estimate (by rounding off to nearest hundreds) and also a closer estimate (by rounding off to nearest tens): 1,08,734 - 47,599​

Answer 1

Step-by-step explanation:

Rounding off to hundreds

Rounding off 1,08,734 to the nearest hundreds= 1,08,700

And rounding off 47,599 to the nearest hundreds= 47,600

On subtracting we get

1,08,700-47,600=61,100

Rounding off to tens

Rounding off 1,08,734 to the nearest tens =1,08,730

Rounding off 47,599 to the nearest tens =47,600

On subtracting we get

1,08,730-47,600=61,130

The answer is 61,000 when we round off the given terms to the nearest hundreds.

The answer is 61,130 when we round off the given terms to the nearest tens
