The average fraction of the students in the two classes is 17/20.

<h3>What is a fraction?</h3>

A fraction is a ratio of two integers called the numerator and denominator.

Analysis:

sum of the fraction of both students in the two classes = 4/5 + 9/10 =

LCM of the denominators which are 5 and 10 is 10

  so the sum of both fractions = 8/10 + 9/10 = 17/10

The average = 17/10 /2 = 17/10 x 2 = 17/20

In conclusion, the average of the fraction of students on both classes is 17/20.

How to solve for x in these shapes?
DiKsa [7]

Answer:

Step-by-step explanation:

a

sum of angles of a quadrilateral=360°

4x+5x+20+5x-10+3x+10=360

17x=360-20

17x=340

x=340/17

x=20

b.

sum of angles= (n-2)×180

where n is the number of sides.

5x+4x+2+5x+6+2x-2+3x+5+x-10=(6-2)×180

20x+1=720

20x=719

x=35.95

HELP PLEASE the answrtr
lesantik [10]

<em>first:</em>

<em></em>\left(\frac{1}{4}+1\frac{1}{2}\right)\cdot \frac{1}{2} =\left(\frac{1}{4}+\frac{3}{2}\right)\cdot \frac{1}{2}  =\frac{\left(\frac{1}{4}+\frac{3}{2}\right)\cdot \:1}{2} =\frac{\left(\frac{1}{4}+\frac{6}{4}\right)\cdot \:1}{2} =\frac{\frac{7}{4}\cdot \:1}{2} =\frac{\frac{7}{4}}{2} =\frac{7}{4\cdot \:2} =\frac{7}{8}<em></em>

<em>So the first is the correct one.</em>
