This video is about the mathematical calculation to convert decimal to percentages. In this video, step by step calculations are shown. Let us take an example of a number; say 0.345, and we want to convert this decimal number to a percentage. Then we have to shift the decimal to two places to right side. We then get the answer in percentage but don't forget to put the sign at last. This video has made it easier for me to make my children understand about the decimals and percentages.
