Out of 32 students in a class, 5 said they ride their bikes to school. Based on these results predict how many of the 800 students in the school ride their bikes in school.
5/32 = x/800 {cross multiply and solve for x.}
HOW CAN WE SAY THAT THE CIRCLE HAVE A STRAIGHT SIDES? YES OR NO?
BIKES Out of 32 students in a class, 5 said they ride their bikes to school. Based on these results, how many of the 800 students in the school ride their bikes to school?
a.
150 students
b.
125 students
c.
100 students
d.
75 students
15
125
To predict how many of the 800 students in the school ride their bikes, we can use the ratio of students who ride their bikes in the class to the total number of students in the class.
First, find the ratio of students who ride their bikes to the total number of students in the class:
Ratio = Number of students who ride their bikes / Total number of students in the class
In this case, the number of students who ride their bikes is 5, and the total number of students in the class is 32.
So, the ratio of students who ride their bikes to the total number of students in the class is:
5/32
Now, we can use this ratio to predict the number of students who ride their bikes out of the 800 students in the school.
Prediction = Ratio x Total number of students in the school
Substituting the values:
Prediction = (5/32) x 800
To simplify the calculation:
Prediction = (5 x 800) / 32
Now, multiply 5 by 800 and then divide by 32:
Prediction = 100
Therefore, based on the results from the class, we can predict that approximately 100 out of the 800 students in the school ride their bikes.
