Variables and Constants in Algebra LITERALS OR VARIABLES The letters used to represent numbers or some other quantities in general are called literal numbers or simply literals. Literals can take any value. They are also called variables.For example, Rohan borrowed x = Rs. 50 from Suresh; Mona got y = 16 candies. Hence, x and y denote numbers and are called literal … [Read more...] about Variables and Constants in Algebra

## Division Of A Line Segment Into A Given Ratio

Division Of A Line Segment Into A Given RatioGiven a line segment AB, we want to divide it in the ratio m : n, where both m and n are positive integers. To help you to understand it, we shall take m = 3 and n = 2. Steps of Construction: 1. Draw any ray AX, making an acute angle with AB. 2. Locate 5(= m + n) points A1, A2, A3, A4 and A5 on AX so that AA1 = A1A2 = … [Read more...] about Division Of A Line Segment Into A Given Ratio
