Question 2 of 5.
Each of the digits 3. 5. 7, and 8 is written on its own card. The four cards are given to a student, and then the student is asked to use the cards to form the largest three-digit number that is greater than 300 and less than 700. In the number formed, what digit will be in the tens place?
A. 3
B. 5
C. 7
D. 8
Explanation: Largest under 700 over 300: 583, tens 8. Other arrangements smaller. Maximizes by placing highest in higher places.

Question 4 of 5.
In the number shown, which of the following is the value of the underlined digit?
A. 9 × 1 ^ - 2
B. 9 × 10 ^ - 2
C. 9 ×100^ 2
D. 9×1.000^ - 2
Explanation: To find the value of the underlined digit in 345.792, first identify the digit. The underlined digit is 9. Next, determine its place value. The digit 9 is located in the hundredths place, which means it represents parts out of one hundred. Place value positions to the right of the decimal point are tenths, hundredths, thousandths, and so on. Since 9 is in the hundredths place, its value can be expressed as a fraction or as a power of ten. The hundredths place corresponds to on, which is equivalent to 10-2. Therefore, the digit 9 in this position represents 9 * 1/100 or 9 * 10 ^ - 2 When simplified, this equals 0.09. This confirms that the value of the underlined digit is 9 * 10 ^ - 2 which correctly represents its place value. 100
