Ming placed a zero in the number 590 because the digit 9 in 59 has a value of 90. When performing the multiplication, she likely carried over the place value and recognized that 590 represents 590 (which includes the value of 90 from the digit 9). Thus, the correct response is:
The digit 9 in 59 has a value of 90.
