The ratio of 7th and 8th graders in a soccer league is 16:24. If there are 200 students in all, how many are 7th graders?
16/40 = x/200
Cross multiply and solve for x.
X=80
To find out how many students are 7th graders, we'll first need to find the total number of parts in the ratio, which is the sum of the two parts: 16 + 24 = 40.
Next, we'll determine the fraction that represents the 7th graders in this ratio by dividing the number of 7th graders (16) by the total number of parts (40): 16/40 = 0.4.
Finally, to find the actual number of 7th graders, we'll multiply this fraction by the total number of students in the league (200): 0.4 * 200 = 80.
Therefore, there are 80 7th graders in the soccer league.
