Question

The table shows the types of notebooks purchased from an office-supply store for one week.

Medium ruled           Narrow ruled
1-subject                    96                        102
3-subject                   51                          67
5-subject                   33                         40

What percent of the narrow-ruled notebooks were 1-subject notebooks?
Round to the nearest percent.

Answer 1

So we have 209 Narrow ruled in total, but only 102 of them are 1-subject. 209/102=2 (rounded) so your answer is 2%
