Understanding Decimals and Percentages
What are Decimals?
Decimals are numbers expressed in the base-10 numeral system. They use a decimal point to separate the whole number part from the fractional part. Each position after the decimal point represents a power of 10 (0.1, 0.01, 0.001, etc.).
What are Percentages?
Percentage means "per hundred" or "out of 100." It's a way of expressing a number as a fraction of 100. The symbol % represents this concept, where 1% = 1/100 = 0.01.
