Where is 0.01 on a number line?

Write 0.01 as hundredths and mark it on a number line. In the above number line, if we divide the distance between two whole numbers (0 and 1) into 100 equal parts, the length of each equal part is 0.01 or 1/100 part. So, one hundredth (1/100) is the 1 st part from zero as marked on the number line above.

How do you find the difference between two decimals?

Subtracting Decimals
