I am a number between 0.23 and 0.31. I have 3 digits. All of my numbers are the same. What number am I?

Since the first digit must be 2 or 3, and 0.222 and 0.333 are outside the range, there appears to be no answer.

Perhaps another teacher will correct me.

I agree with drwls

To find the number between 0.23 and 0.31 that has three digits and all of its numbers are the same, we need to narrow down the possibilities.

Since the number has three digits, it must fall between 0.23 and 0.31. To have three digits, the hundredths digit must be the same as the tenths digit and the same as the thousandths digit.

Let's go through the possibilities. Since the tenths digit and thousandths digit are the same, they can only be 2, 3, or 1. However, the number we are looking for falls between 0.23 and 0.31, so the tenths digit cannot be 1.

Therefore, the possible numbers that satisfy the conditions are 0.22, 0.23, 0.24, 0.33, 0.44, 0.55, 0.66, 0.77, 0.88, and 0.99.

Among these numbers, the only value that falls between 0.23 and 0.31 and has three repeating digits is 0.33.

So, the number you are is 0.33.
