Here are the essential concepts you must grasp in order to answer the question correctly.
Fractions
A fraction represents a part of a whole and is expressed as a ratio of two integers, with the numerator (top number) indicating how many parts are taken and the denominator (bottom number) showing the total number of equal parts. To express a fraction in its lowest terms, one must divide both the numerator and denominator by their greatest common divisor (GCD).

Decimals
Decimals are another way to represent fractions, particularly those with denominators that are powers of ten. A decimal is written with a decimal point separating the whole number part from the fractional part. For example, the fraction 1/4 can be expressed as 0.25 in decimal form, which is useful for calculations and comparisons.

Percentages
A percentage is a way of expressing a number as a fraction of 100, denoted by the symbol '%'. To convert a fraction or decimal to a percentage, you multiply it by 100. For instance, 20% means 20 out of 100, which can also be represented as the fraction 1/5 or the decimal 0.20.
