The two-way table shows the information of 300 users that played the game "Equation IQ"
(you can determine this number by adding all values on the total column, or total row)
The students that are in grade 8, who were successful 51% or more of the time, are those included in the last two intervals, that is, 51-75% and 76-100%
The ratio can be determined as the number of students of 8 grade that achieved 51% or more divided by the total number of people that played the game.
[tex]\frac{36+69}{300}=\frac{105}{300}=\frac{7}{20}\approx0.35[/tex]
The ratio of students in eight grade that were successful 51% or more is 7/20
