To calculate equivalent fractions, take a fraction and divide or multiply both of its numbers by the same figure. An action must always be performed to both parts of the fraction when calculating equivalent figures.
Divide the fraction by figures that both the numerator and denominator are divisible by
With 20/30, both the top and bottom numbers are divisible by 2, 5 and 10. Dividing the fraction by 2 yields 10/15, while dividing it by 5 provides 4/6. Using 10 as a divisor gives 2/3.
Multiply the numerator and denominator by the same number
Finding equivalent fractions through multiplication yields an infinite amount of possibilities. If 20/30 is multiplied by 2, this equals an equivalent fraction of 40/60.Learn more about Fractions & Percentages
