Mr. smith has 5 courses he teaches at the community college. his course a has 102 students with an average tardiness of 3 studen

Furkat [3]

The percentage of tardiness among the 102 pupils is 2.94.

<h2>Calculation of the percentage</h2>

According to the query,

Course A: Total number of students = 102

Number of tardy students = 3

Percent of students tardy in course A = (number of tardy students/total

number of students) * 100

=(3/102)*100

= 2.941

≈2.94

In case of course B: Total number of students = 85 & tardy student = 5

So, the percent of tardy student = (5/85)*100 = 5.88 %

Therefore, it is concluded that the percentage of student tardiness in course A is 2.94.

kolezko [41]

<h3>Answer : </h3>

$\Large \pink{\tt \dfrac{35}{36}}$

<h3>Solution :</h3>

$\tt \dfrac{3}{4} + \dfrac{2}{9}$

By taking LCM = 4 × 9 = 36

$\tt = \dfrac{3 \times 9}{4 \times 9} + \dfrac{2 \times 4}{9 \times 4}$

$\tt = \dfrac{27}{36} + \dfrac{8}{36}$

$\tt = \dfrac{27 + 8}{36}$

$\tt = \dfrac{35}{36}$

$\pink{\tt \therefore \: Answer \: is \: \dfrac{35}{36}}$
