Answer:
Greatest percentage of grammar question is finished by Ethan that is 28.57%.
Solution:
Given that Michael finished 19% of grammar questions assigned.
Ethan finished 2 out of 7 grammar questions
And Tommy finished 0.24 of grammar questions.
Need to determine who finished greater percentage of his grammar question.
So for comparison, we need to calculate finished questions in % for each of the student.
No calculation required in case of Michael as data is already provided in percentage that is 19%.
For Ethan, percentage of finished question is given as:
[tex]=\frac{\text {number of question finished}}{\text {number of total questions}} \times 100[/tex]
[tex]\frac{2}{7} \times 100=\frac{200}{7}=28.57 \%[/tex]
Let’s assume number of grammar question assigned to Tommy = x.
As Tommy finishes 0.24 of grammar questions, it means Tommy finished [tex]0.24 \times x = 0.24x[/tex] of questions
So percentage of questions finished by Tommy is given as:
[tex]\frac{0.24 x}{x} \times 100=24 \%[/tex]
On comparing the three percentages we can clearly say that greatest percentage of grammar question is finished by Ethan that is 28.57%.
