Fractions and percentages are important mathematical concepts used in school exercises, everyday calculations, shopping, finance and many other situations. Online calculators can help you check your answers and perform calculations quickly.
How to Simplify Fractions
Simplifying a fraction means writing it in its lowest terms without changing its value. Divide the numerator and denominator by their greatest common divisor. For example, the fraction 12/18 becomes 2/3 after dividing both numbers by 6.
How to Add Fractions
To add fractions with the same denominator, add their numerators and keep the denominator unchanged. For fractions with different denominators, first find a common denominator. Then add the numerators and simplify the result if possible.
How to Calculate a Percentage
A percentage represents a value out of 100. To calculate a percentage of a number, multiply the number by the percentage and divide by 100. For example, 20% of 150 is (20 x 150) / 100 = 30.
