decimal to percent

-->

There are several mathematical operations that we can do with decimal numbers. If we are asked to find the percentage for any given decimal, then decimal is multiplied with 100 to get the desired %. Position of the decimal in the number is shifted to right of the original position skipping two digits after decimal. For instance, suppose we have a decimal number 00.4887, then equivalent percent is calculated as follows:

00.4887 x 100 = (4887 /10000) x 100 = 4887 /100 = 48.87 %.

Let us take one more example of decimal to percent conversion: Convert 2.02 to its equivalent %. We multiply 2.02 and 100: 2.02 x 100 = 202 %

Application of this is found in many mathematical problems where the rate or percentage evaluation is needed to be done.

Linear equations are those expressions in maths which when plotted result into a straight geometrical line. The commonly used form of any linear equation is the slope – intercept form that is given as: y = m x + c. Where, m denotes the slope and c denotes the intersection point of the line when it is graphed. On the basis of the slope and the intercept of the line we can decide whether the two lines are intersecting, parallel or coinciding. If the two lines have different slopes, then only we can use the linear equation solver to find the intersection point. There can be just one intersection point between two lines. In case the slopes are equal, the lines can be either coinciding or parallel.

If the intercepts of the lines are also equal, then the lines are said to be coinciding and for lines with different intercepts we call them parallel. These concepts form the base of algebra and geometry of maths and have been briefed in the cbse sample papers 12.
