Answer:
Since 8 is in the thousandths place, the value of the digit is 0.008.
Step-by-step explanation:
In order to answer this question, we first need to know which place each digit would be in:
Next, we can conceptualize 3.458 better by thinking of it as: 3+0.4+0.05+0.008, which is the same as adding all of its parts individually. From here, we can see that 0.008 is the value of the 8, and since it is in the thousandths place (we know this because it is the 3rd digit to the right of the decimal), we can say that since 8 is in the thousandths place, the value of the digit is 0.008.
