Kate is thinking of a number that is less than 40. It has 8 ones and some tens. what could be kates number?
It will be x8
where the tens digit x < 4
So, what do you think?
10x + 8 < 40
10x < 32
x < 3.2
so x could be 1, 2, or 3
and her number would be 18, 28, or 38
Im in the 2nd grade I'm doing tens and ones.
To find the possible numbers that Kate could be thinking of, we need to consider that it has 8 ones and some tens, and it is less than 40.
First, let's consider the possible values for the tens place. Since the number is less than 40, the tens digit can be any value from 0 to 3.
If the tens digit is 0, then the number would be something like 8 (since it has 8 ones and 0 tens).
If the tens digit is 1, then the number would be something like 18 (8 ones with 1 ten).
If the tens digit is 2, then the number would be something like 28 (8 ones with 2 tens).
If the tens digit is 3, then the number would be something like 38 (8 ones with 3 tens).
So, the possible numbers that Kate could be thinking of are 8, 18, 28, and 38.
