Hi Ashley,
Since we are given four numbers and asked which is the least, we should order the numbers from least to greatest:
22<23<41<76. We read this as "22 is less than 23, which is less than 41, which is less than 76."
We have therefore reasoned than 22 is the smallest number and 76 is the greatest number.
∴22 is the number that has the least value.
Best,
