During the first part of a hike, andre drank 1.5 liters of the water he brought. if this 50% of the water he brought, how much did he bring?

3 liters

Step-by-step explanation:

if 1.5 liters is 50% of the original amount, then to find the original amount you must multiply by two, or:

1.5 liters ×2=3 liters

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.

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
