Tenths and hundredths.
The big ideaTenths come first after the point, hundredths second. Ten hundredths make one tenth.

How it works

Tenths come first after the point. Hundredths come second.

Ten hundredths make one tenth.

0.89 is 89 hundredths, which is 89/100.

5/10 is shaded
5 of 10 parts shaded: 0.5.

Example 1: Read a shaded part

  1. A bar has 10 equal parts and 5 are shaded.
  2. 5 of 10 is 5/10.
  3. As a decimal that is 0.5.

Example 2: Write as a fraction

  1. Write 0.89 as a fraction.
  2. The decimal 0.89 has two places after the point.
  3. Two places means hundredths.
  4. So the answer is 89/100.

Example 3: Add a tenth and a hundredth

  1. Add 7/10 and 6/100 as a decimal.
  2. 7/10 is 0.7 and 6/100 is 0.06.
  3. 0.7 + 0.06 = 0.76.
  4. So the answer is 0.76.
