               If rounding to the tens
To estimate round 324 and 285 to the nearest ten.
320 - 290 
Then subtract 320 - 290 =
30

Answer:

30

Step-by-step explanation:

324-285

WE can estimate the numbers to nearest tens or nearest hundreds

LEts estimate the numbers to nearest  tens and find the difference

324 round to nearest tens is 320

285 have 5 in once place that is equal to 5 so we add 1 with 8

285 round to nearest tens is 290

Now we find the difference

\(320- 290= 30\)

The difference is 30

If we estimate to nearest hundred then 300 -300 becomes 0
