The ratio of parents to students of 4:5. If there are 189 total spectators to the game,how many of them are parents. How many of them are students.
4/9 = p/189
Cross multiply and solve for p to find the number of parents at the game.
84 parents
105 students
Right.
To find the number of parents and students among the spectators, we will use the ratio between parents and students.
Given that the ratio of parents to students is 4:5, we can assume that the total number of parts that make up the ratio is 4 + 5 = 9.
To find the number of parents, we will divide the total number of spectators by the sum of the ratio parts and then multiply it by the number of parts representing parents.
Number of parents = (Total spectators / Sum of ratio parts) * Number of parts representing parents
= (189 / 9) * 4
= 21 * 4
= 84
Hence, there are 84 parents among the spectators.
Now, to find the number of students, we will multiply the number of parents by the ratio between students and parents.
Number of students = Number of parents * (Ratio parts representing students / Ratio parts representing parents)
= 84 * (5 / 4)
= 84 * 1.25
= 105
Therefore, there are 105 students among the spectators.
