Writing a ratio as a percent, step by step

A percent is nothing more than a ratio out of a hundred, so writing 3.

The question

19 : 25 = 76%

19 : 25▢ : 100
19× 4 =76
19 : 25=76%
  1. Percent means "out of a hundred", so this is asking what 19 : 25 would be if the second number were 100.
  2. 25 × 4 = 100, so scale the other side by the same 4: 19 × 4 = 76.
  3. So 19 out of 25 is 76 out of a hundred — 76%.

How it works.

  1. 01

    Percent means "out of a hundred", so this is asking what 19 : 25 would be if the second number were 100.

  2. 02

    25 × 4 = 100, so scale the other side by the same 4: 19 × 4 = 76.

  3. 03

    So 19 out of 25 is 76 out of a hundred — 76%.
