5/20....an equivalent fraction would be 1/4...I simply reduces it. To find the percent, simply divide 1 by 4, which gives u 0.25.....and multiply that by 100 to give u ur percent...which is 25% (u multiply the decimal by 100 to get the percent)
9/25....since it will not reduce, multiply both numerator and denominator by the same number to get an equivalent fraction...9/25 * 2/2 = 18/50.
For the percent (u can use either fraction)....9/25...divide 9 by 25 and u get 0.36....multiply by 100 to get ur percent of 36%
9/6....reduces to 3/2.
3/2 = 1.5 = 150%
