Shown Below

Step-by-step explanation:

The Whole number can be put over one to make multiplying easier.

1-     4/5 times 20/1 = 80/5= 16

2-    5/10 times 19/1=  95/10= 9.5

3-    2/3 times 6/1= 12/3= 4

4-    5/10 times 8/1= 40/10= 4

5-    4/6 times 16/1= 64/6= 10 2/3

6-    4/10 times 4/1= 16/10= 1 3/5

7-    2/8 times 15/1= 30/8= 3.75

8-    4/5 time 2/1= 8/5= 1.6

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
