Negative zero point four nine five.
Work Step by Step
The '$-$' sign at the starting of the number indicates that the number is negative. Therefore while writing it in words, we need to write the word negative. Followed by the negative sign is 0 $=$ Zero. Then comes the decimal point. While reading or writing the same, we need to say or write only 'point' and not the 'decimal point'. Example= 1.2 is read as One point two. After the point, we have to write all the digit's name individually. Example= 1.234 is One point two three four and NOT One point two hundred thirty-four. Therefore 4 $=$ Four 9 $=$ Nine 5 $=$ Five. So, Negative zero point four nine five is the final answer.
