The question
Question: compare 275 and 257.
Compare 275 and 257
1 Line up the places
We line up the ones under the ones, the tens under the tens, and so on.
2 Compare from the left
275 and 257 are the same in the first place.
Look at the tens: 7 is more than 5.
So 275 is greater than 257.
275 > 257
3 Write it with a sign
So 275 > 257.
= 275 > 257
