What is the value of the underlined digit
6,560

Answer: 6,000
Please be so kind as to check the above and let me know if I made any mistakes.
You made a mistake in the first question. The correct answer is that Marco drew 15 pictures in art class, not 17. To calculate this, you multiply the total number of pictures drawn by the fraction that represents the percentage drawn in art class. In this case, since 3/4 represents 75%, you calculate 20 x (3/4) = 15. So, Marco drew 15 pictures in art class.
The second question is correct. One half of 10 marbles is indeed 5 marbles.
In the third question, you underlined the digit 6 in the number 6,560. To determine the value of this underlined digit, you look at its position in the number. In this case, the digit 6 is in the thousands place. The place value of the thousands is 1,000. Therefore, the value of the underlined digit is 6 x 1,000 = 6,000. So, the correct answer is 6,000.
