📐 Finding the Midpoint Between Two Points
This paragraph introduces the concept of finding the midpoint between two points in a coordinate system. It provides a step-by-step guide on how to calculate the midpoint using the average of the x-coordinates and y-coordinates separately. The example given uses points A (2,6) and B (4,10), leading to a midpoint of (3,8). The explanation continues with another example, where the midpoint between points A (3,5) and B (9,1) is calculated to be (6,3). The paragraph concludes with an encouragement to try finding the midpoint between two additional points involving negative numbers: (-4,2) and (8,-6).
🔍 Calculating Midpoints with Fractions
This section delves into finding midpoints between points that have fractional coordinates. It starts with an example involving points A (1/3, 2) and B (5, -1/4), guiding the viewer through the process of averaging the fractions to find the midpoint's x and y coordinates. The x-coordinate is simplified to 8/3, and the y-coordinate to 7/8. The paragraph then presents a more complex example with points A (1/5, -2/3) and B (4/3, 3/4), where the midpoint's x-coordinate is calculated as 23/30 and the y-coordinate as 1/24. The explanation emphasizes the importance of finding a common denominator and simplifying the fractions to arrive at the correct midpoint coordinates.
📚 Advanced Midpoint Calculation with Mixed Fractions
