5/6 of an hour is 50 min. So 50 times 3 equals 150 min for reading. 3/4 of an hour is 45 min. 45 times 2 equals 90 min for science. And 1/2 of an hour is 30 min. So 30 times 4 equals 120 mins for math. Add 150,90, and 120 min all together and you get 360 mins total. Divide 360 by 60, and you get 6 hours total that Michaela spent on reading, math, and science. Not 2 1/2.
When we talk about free form shapes, it can be curve, lines or simple concave or convex polygons.
1. The shape can be closed or open.
2. The curve can cross each other, that is lines or doodled lines may intersect.
3. The free form shape consist of either lines or doodled lines, which we call an open curve.
When we talk about Geometric Shapes, it consist only of Polygons, which consist of triangles, Quadrilaterals, polygons.
1. The curve is simple closed curve.
2. It consist entirely of line segments.
3. The intersection within the curve is a point.
