Find three decimals strictly between \(4.12\) and \(4.13\) that each have exactly three decimal places. Then order all five numbers from least to greatest using \(<\).

Hints

- Rewrite both endpoints with three decimal places. - Consider the thousandths between \(120\) thousandths and \(130\) thousandths. - Arrange your chosen values in increasing order.

Solution

1. Write the endpoints to the thousandths place: \(4.12 = 4.120\) and \(4.13 = 4.130\). 2. Choose any three thousandths between \(4.120\) and \(4.130\), such as \(4.121\), \(4.125\), and \(4.129\). 3. Order the five values.

Answer

Answers will vary. One possible answer is \(4.12 < 4.121 < 4.125 < 4.129 < 4.13\).

Replace both boxes with the same digit. Find all digits that make the inequality true: \(4.2<4.\square5<\square.1\)

Hints

- Split the compound inequality into two separate inequalities. - Test how the same digit affects each number. - Line up decimal places by adding a trailing zero when needed.

Solution

1. The first inequality is \(4.2<4.\square5\). Writing \(4.2\) as \(4.20\) shows that this is true when \(\square\ge 2\). 2. For the second inequality, \(4.\square5<\square.1\), the values \(2,3,4\) do not work because the number on the right is less than or equal to \(4.1\). When \(\square=5\), \(4.55<5.1\), and any larger digit also works. 3. Therefore, the digits that satisfy both inequalities are \(5,6,7,8,9\).

Answer

The possible digits are \(5,6,7,8,9\).
5121645
The same digit must replace both boxes in the compound inequality \(0.\square7<0.\square<0.6\). Explain mathematically why no digit can make the statement true.

Hints

- Focus first on \(0.\square7<0.\square\). - Adding a trailing zero does not change the value of a decimal. - Compare the digits from left to right by place value.

Solution

1. Consider only the first inequality: \(0.\square7<0.\square\). 2. Write the number on the right with a trailing zero: \(0.\square7<0.\square0\). 3. The tenths digits are identical, but the hundredths digit on the left is \(7\) and the hundredths digit on the right is \(0\). Therefore, \(0.\square7\) is always greater than \(0.\square0\). 4. The first inequality is impossible for every digit, so the entire compound inequality has no solution.

Answer

No digit works. The first inequality is impossible because \(0.\square7\) is always greater than \(0.\square=0.\square0\).

For \(72.043\), state the whole-number part and the tenths, hundredths, and thousandths digits. Then read the decimal using place-value words.

Hints

- Separate the whole-number part from the digits after the decimal point. - Use the thousandths place to name the fractional part.

Solution

1. The whole-number part is \(72\). 2. The tenths, hundredths, and thousandths digits are \(0\), \(4\), and \(3\). 3. The fractional part is \(43\) thousandths, so the decimal is read as “seventy-two and forty-three thousandths.”

Answer

Whole-number part: \(72\); tenths digit: \(0\); hundredths digit: \(4\); thousandths digit: \(3\); reading: “seventy-two and forty-three thousandths.”
