Hey there,
my question is:
do i always have to compare the answer of the multiplied prime numbers by dividing the numerator and denominator with the given answers to see which one is correct. or is there a way to to always see the accurate answer without having to compare them.
here is my way of reducing fractions, feedback would be appreciated I'm pretty new to this.
lets take 108/162
108:2=52:2=27:3=9:3=3
2x2x3x3 = 36
162:2=81:3=27:3=9:3=3
2x3x3x3 = 54
108:36 = 3
162:36 = 4.5
108:54 = 2
162:54 = 3
I feel like I'm doing something incorrect, as i seem to stumble up on some issues with certain fractions like 78/91
78:2=39:3=13
91:7= 13
i don't see why i am supposed to divide this one by 13, if the formula used above are for other fractions.
