use symbols to compare the numbers 512 and 521. write the comparison to ways. then explain your thinking

Solution: - Given numbers to compare are 512 and 521.

As they are 3 digit numbers

So, we have to compare hundreds place.

But hundreds are equal in both the numbers with digit 5.

Next we have to compare tens place.

Case 1 : - 1 ten is smaller in 512 than 2 tens in 521.

So we get the result that,

512 is smaller than 521

or 512 < 521

Case 2:-2 tens is greater in 521 than 1 ten in 512.

So we get the result that,

521 is greater than 512

or 521 > 512
