A reasonable estimate could be turning 2/5 into 2/4 (1/2) then subtracting it to give you 3 3/4 - 2/4 = 3 1/4.


To prove this estimate is reasonable, the actual answer to the problem is 3 7/20, which is pretty close to 3 1/4! (Could be written as 3 5/20)

Aleonysh [2.5K]

Answer: hope this help's

Step-by-step explanation:

Geometry Terms Chapter 3

A B

Coplanar in the same plane

Parallel lines coplanar lines that do not intersect

Intersecting lines coplanar lines that have exactly one point in common

Perpendicular lines lines that intersect at righ- are non-coplanar

- they are not parallel and do not intersect

t angles     are non-coplanar

- they are not parallel and do not intersect

- planes that do not intersect        - two segments are parallel if the lines containing them are parallel           - a line that intersects two or more coplanar lines at different points

- transversal has nothing to do with whether lines are parallel or not          - an angle formed between parallel lines by a third line that intersects them

lie on the same side of the transversal and in corresponding positions

alternate exterior angles

- non-adjacent exterior angles that lie on opposite sides of the transversal

10/56     hope this help you a lot better
