To arrange the numbers 23, 76, 18, and 910 from least to greatest, we start by comparing each of the values. The steps are as follows:
- First, we identify the smallest number. Here we have 18, which is less than both 23 and 76, and distinctly less than 910.
- Next, we evaluate the remaining numbers: 23 and 76. Between these, 23 is the smaller value.
- Then we compare 23 and 76. Since 23 is lesser, we place it next in line.
- Lastly, we consider 910, which is significantly greater than all the previous numbers.
So, when we list them in order from least to greatest, it becomes:
18, 23, 76, 910.
