practice converting visual data into binary and decimal. The graph paper tables below represent data in a visual format. Each table below is a visual represenatation of 8 bytes, one byte per row. Each column in the row represents a single bit. The final entry in the table is for the decimal number represented in the row and is not part of the byte. An example: |x||X| |X|| 42 Instructions 1. For table one take a pencil and draw a numeral using as much of the graph paper as possible. Mark any square that contains a line with a large X or fill in the square. 2. For table two draw an emoji with a pencil using the entire graph paper and mark squares that contain a line with a large X or fill in the blocks. 3. For an example of "drawing" refer to table three; it contains the letter 4. Convert the visibile bits (Marked with an X) to decimal on table three. Fill in the values in the space provided. 5.
