Anumber of students from sms are participating in a community service project. the ratio of 8th graders to 6th graders is 5: 3 and the ratio of 8th graders to 7th graders is 8: 5. what is the smallest number of students that participated?

The smallest number of students that participated in community service project is 89

Solution:

Given that,

The ratio of 8th graders to 6th graders is 5:3 and the ratio of 8th graders to 7th graders is 8:5

We have to find what is the smallest number of students that participated?

Now, given ratios can be converted to fractions.

a : b can be converted to fraction as

On inversing we get,

On inversing we get,

Now, add both the fractions

Now, we want least number of students, then we have to take from above fraction,

6th graders + 7th graders = 49  

And 8th graders = 40,  

Then, total students = 6th graders + 7th graders + 8th graders = 49 + 40 = 89

Hence, 89 students participated.

answer: y=4000x+14000

step-by-step explanation:

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
