Which fraction has the greatest value and how did u get the answer....1/8,5/12,9/10

Answer 1

do a rough comparison:
1/8 is much less than 1/2
5/12 is almost 6/12 = 1/2
9/10 is almost 1, which is > 1/2

convert to decimal:
1/8 = 0.125
5/12 = 0.417
9/10 = 0.900

convert to LCD(8,10,12) = 120
1/8 = 15/120
5/12 = 50/120
9/10 = 108/120
