ML Aggarwal Solutions for Class 8 Maths Chapter 7 Percentage

The word comes from the Latin phrase per centum, which means per hundred. This time the table includes percents. The term 'per cent' means one out of a hundred. In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the per cent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" is also used. A percentage is a dimensionless number; it has no unit of measurement. If you have to turn a percentage into a decimal, divide by 100. For example, 25% = 25/100 = 0.25.


Percentages are used widely and in many different areas. For example, discounts in shops, bank interest rates, rates of inflation and many statistics in the media are expressed as percentages. Percentages are essential for understanding the financial aspects of everyday life. Therefore, any business involving tax calculation, tip calculation, or interest rates uses fractions. Banks, restaurants, movie theatres and department stores all use percentages, so teller, wait staff and store clerk positions are included here.
