How do you represent a decimal on a number line?

Answer 1

One way of doing it would be do put smaller tick marks in between the larger tick marks for whole numbers. So if you want to represent, 1, then 1.25, 1.50, 1.75 then 2 on a number line, you could put a large tick mark with the number '1' above it, then 3 evenly space smaller tick marks, then another large tick mark with the number '2' above it. If you have enough room, you could write the decimal numbers above the smaller tick marks, too.
