The percentages in this problem are defined as follows:
- 155 poems: 100% of 155 poems.
- 31 poems: 20% of 155 poems.
- 186 poems: 120% of 155 poems.
A percentage is calculated as the division of the number of desired outcomes by the number of total outcomes, which is then multiplied by 100% to convert the proportion to a percentage.
From the tape diagram given at the end of the answer, the total number of outcomes is given as follows:
155 poems.
Hence the percentage of 155 poems is of:
155/155 x 100% = 100%.
The percentage of 31 poems is of:
31/155 x 100% = 20%.
The percentage of 186 poems is of:
186/155 x 100% = 120%.
