Top number of the fraction

Bottom number of the fraction (cannot be zero)

Decimal = Numerator ÷ Denominator | Percentage = Decimal × 100 | Simplify: divide both by GCD
For 3/4: Decimal = 3 ÷ 4 = 0.75, Percentage = 0.75 × 100 = 75%, Simplified = 3/4 (already simplest form)

How do you convert a fraction to a decimal?

To convert a fraction to a decimal, divide the numerator (top number) by the denominator (bottom number). For example, 3/4 = 3 ÷ 4 = 0.75. If the division results in a repeating decimal, you can round to the desired number of decimal places. For example, 1/3 = 0.333...

How do you convert a decimal to a percentage?

To convert a decimal to a percentage, multiply by 100 and add the % symbol. For example, 0.75 × 100 = 75%. This works because "percent" means "per hundred," so 0.75 = 75/100 = 75%.

How do you convert a percentage to a fraction?

To convert a percentage to a fraction, write the percentage as a fraction over 100, then simplify. For example, 60% = 60/100 = 3/5 (dividing both by 20). For percentages with decimals like 12.5%, first convert: 12.5/100 = 125/1000 = 1/8.

What is the easiest way to simplify fractions?

To simplify a fraction, find the Greatest Common Divisor (GCD) of the numerator and denominator, then divide both by the GCD. For example, to simplify 12/18: GCD(12, 18) = 6, so 12/18 = (12÷6)/(18÷6) = 2/3. This gives you the fraction in its lowest terms.
