How to Put Rational Numbers in a Number Line
- 1). Draw a horizontal line. Put the value of zero in the middle of the number line. To the left of zero, put
the negative integers up to -10. To the right of zero, put the positive integers up to 10. These are known as major tic marks. - 2). Put three minor tick marks between the zero and the one. Since the numbers have been divided by
four, the bottom of the fraction should be four for each of the tic marks,1/4, 2/4, and 3/4. Reduce the 2/
4 to 1/2. The same process repeats for the other numbers, however the whole number to the left also writes as in 1 1/4, 1 1/2 and 1 3/4. - 3). Convert the fractions to decimals and write the decimal equivalents above. Divide the numerator by the
denominator to change fractions to decimals -- 1/4 is .25, 1/2 is .50, 3/4 is .75. Repeat the process for the rest of the numbers. - 4). Use the number line as a reference to convert between fractions and decimals or as a visual learning tool.
