To find the fraction of sixth-graders who play sports, we need to convert the percentage into a fraction.
Given that Landry discovered that 35% of sixth-graders play sports, the fraction can be written as 35 over 100.
Therefore, the correct response is B: 35 over 50.
To determine the fraction of sixth-graders that play sports, we need to convert the given percentage (35%) into a fraction.
To convert a percentage into a fraction, divide the percentage by 100. In this case, we divide 35 by 100:
35 ÷ 100 = 0.35
Now, we have a decimal fraction (0.35). However, the question asks for a fraction, so we need to convert the decimal fraction into a fraction.
Since the decimal fraction is less than 1, we can write it as a fraction with the decimal as the numerator and a denominator of 1.
0.35 can be written as 35/100.
However, the fraction 35/100 can be simplified further. Both the numerator and denominator are divisible by 5:
35 ÷ 5 = 7
100 ÷ 5 = 20
So, the fraction 35/100 can be simplified to 7/20.
Therefore, the fraction of sixth-graders that play sports is 7/20.
Based on the given options, the correct response is:
A. 720 as a fraction is 7/20.
