What number has 2 more tens than 11

The answer would be 31.

Let's break down the place values of the numbers involved in the number 11.

11

1 = Tens

11

1 = Ones

The problem says a number with 2 more tens. So we have to add 2 to the number in the tens place.

1+2 = 3

The number is then 31.

Another way to think about this is 2 tens is equal to 20. So it basically says, what number is 20 more than 11.

20 + 11 = 31

In the number 11, the tens place is the first 1 from the left. The ones place is the 1 that is the first from the right. To get a number that is 2 more tens, that would put a 3 in the tens spot. The resulting number with 2 more tens than 11 would be 31.
