Explanation:

Step1: Analyze place - value of 3 in 5,634.18

The 3 in 5,634.18 is in the tens place, so its value is 30. We want a number with a 3 whose value is 10 times 30, i.e., 300. In 53,920.46, the 3 is in the thousands place with a value of 3000. In 892,065.37, the 3 is in the tenths place. In 94,306.12, the 3 is in the hundreds place with a value of 300. In 278,463.9, the 3 is in the ones place. So the answer to question 1 is B.

Step2: Analyze place - value of 7 in 8,054.759

The 7 in 8,054.759 is in the tenths place with a value of 0.7. We want a number with a 7 whose value is $\frac{1}{10}$ of 0.7, i.e., 0.07. In 56,973.08, the 7 is in the tens place. In 6,809.457, the 7 is in the thousandths place with a value of 0.007. In 195,607.4, the 7 is in the ones place. In 42,850.673, the 7 is in the hundredths place with a value of 0.07. So the answer to question 2 is D.

Step3: Analyze place - value of 8 in 83,792.1

The 8 in 83,792.1 is in the ten - thousands place with a value of 80,000. We want a number with an 8 whose value is 100 times 80,000, i.e., 8,000,000. In 846,210.5, the 8 is in the hundred - thousands place. In 168,093.4, the 8 is in the thousands place. In 8,723,501.9, the 8 is in the millions place with a value of 8,000,000. In 52,879.103, the 8 is in the hundreds place. So the answer to question 3 is C.

Step4: Analyze place - value of 2 in 619,250.34

The 2 in 619,250.34 is in the hundreds place with a value of 200. We want a number with a 2 whose value is $\frac{1}{10}$ of 200, i.e., 20. In 891,032.7, the 2 is in the ones place. In 15,329.406, the 2 is in the tens place with a value of 20. In 372,059.8, the 2 is in the thousands place. In 428,316.57, the 2 is in the ten - thousands place. So the answer to question 4 is B.

Step5: Analyze place - value of 5 in 73,256.14

The 5 in 73,256.14 is in the tens place with a value of 50. We want a number with a 5 whose value is $\frac{1}{100}$ of 50, i.e., 0.5. In 86,940.571, the 5 is in the tenths place with a value of 0.5. In 132,598.6, the 5 is in the hundreds place. In 9,305,428, the 5 is in the thousands place. In 674,025.3, the 5 is in the ones place. So the answer to question 5 is A.

Step6: Analyze place - value of 4 in 254,096.3

The 4 in 254,096.3 is in the thousands place with a value of 4,000. We want a number with a 4 whose value is 10 times 4,000, i.e., 40,000. In 5,012,473.6, the 4 is in the hundreds place. In 24,603.157, the 4 is in the thousands place. In 7,345,021.8, the 4 is in the ten - thousands place with a value of 40,000. In 490,327.61, the 4 is in the hundred - thousands place. So the answer to question 6 is C.
