Explanation:

You posted an incomplete question with little and unclear details.

I will answer this question with a more complete version (see attachment)

Given that:

`Scores: 100\ 95\ 88\ 62\ 76\ 90\ 100\ 58\ 72\ 60\ 85\ 90\ 70\ 72\ 54\ 100\ 60\ 80\ 75\ 51`

Required

The fraction that passed the test

Rearrange the score in ascending order:

`Scores: 51\ 54\ 58\ 60\ 60\ 62\ 70\ 72\ 72\ 75\ 76\ 80\ 85\ 88\ 90\ 90\ 95\ 100\ 100\ 100`

The total number of students is:

`n =20`

Extract the students that passed (scored 70 and above)

`Passed: 70\ 72\ 72\ 75\ 76\ 80\ 85\ 88\ 90\ 90\ 95\ 100\ 100\ 100`

Their numbers are:

`Passed: 14`

So, the fraction of those that passed is:

`Fraction = (Passed)/(n)`

`Fraction = (14)/(20)`

Reduce fraction

`Fraction = (7)/(10)`
