Concept Check In Exercises 1–4, provide the correct response.
In the decimal number 367.9412, name the digit that has each place value.
a. tens
b. tenths
c. thousandths
d. ones or units
e. hundredths
(a)
Expert Solution
To determine
The digit from the decimal
Answer to Problem 1E
Solution:
The digit that has tens place value is 6.
Explanation of Solution
Given Information:
The decimal number is
Consider the decimal,
Rewrite the decimal as the sum of digits,
For the tens place, the digit is two places left of the decimal point. Here, it is 6. Hence, the digit at the tens place is 6.
(b)
Expert Solution
To determine
The digit from the decimal
Answer to Problem 1E
Solution:
The digit that has tenths place value is 9.
Explanation of Solution
Given Information:
The decimal number is
Consider the decimal,
Rewrite the decimal as the sum of digits,
For the tenths place, the digit is one place right of the decimal point. Here, it is 9. Hence, the digit at tenths place is 9.
(c)
Expert Solution
To determine
The digit from the decimal
Answer to Problem 1E
Solution:
The digit that has thousandths place value is 1.
Explanation of Solution
Given Information:
The decimal number is
Consider the decimal,
Rewrite the decimal as the sum of digits,
For the thousandths place, the digit is three places right of the decimal point. Here, it is 1. Hence, the digit at thousandths place is 1.
(d)
Expert Solution
To determine
The digit from the decimal
Answer to Problem 1E
Solution:
The digit that has ones place value is 7.
Explanation of Solution
Given Information:
The decimal number is
Consider the decimal,
Rewrite the decimal as the sum of digits,
For the ones place, the digit is one place left of the decimal point. Here, it is 7. Hence, the digit at ones place is 7.
(e)
Expert Solution
To determine
The digit from the decimal
Answer to Problem 1E
Solution:
The digit that has Hundredths place value is 4.
Explanation of Solution
Given Information:
The decimal number is
Consider the decimal,
Rewrite the decimal as the sum of digits,
For the hundredths place, the digit is two places right of the decimal point. Here, it is 4. Hence, the digit at hundredths place is 4.
