Tell me step by step how to change a mixed fraction to an improper fraction using an example. PLS HELP I NEED it I give you 15 points

Step-by-step explanation:

say you have 1 1/4 what you would do is you would multiply 4*1 which is 4+ the top number of the fraction which is 4+1= 5 so now your fraction in is 5/4 .

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.
