4/7 = 0.57,
5/13 = 0.38,
6/11 = 0.54,
3/5 = 0.6,
2/3 = 0.67
Clearly, the second smallest fraction is 6/11.
5/7 = 0.71,
7/13 = 0.54,
4/7 = 0.57,
4/15 = 0.27,
9/14 = 0.64
Clearly, 4/7 is the third highest fraction.
0.8268 = (8268 - 82)/9900
= 8186/9900
= 4093/4950
0.27 = (27 - 2)/90 = 25/90 = 5/18
0.5 =5/9
75/100 = 0.75
9.467 = 9 + (467 - 46)/900
= 9 + 421/900
= 9421/900
= 0.142857 / 0.285714
= [(142857 / 999999) / (285714 / 999999)]
= 142857 / 285714
= 1 / 2
0.252525 ..... = 0.25= 25/99
1/3 + 1/15 + 1/35 + 1/63 + 1/99
= [1/3 + 1/15] + 1/35 + 1/63 + 1/99
= [6/15 + 1/35] + 1/63 + 1/99
= 45/105 + 1/63 + 1/99 = [3/7 + 1/63] + 1/99
= 28/63 + 1/99 = 4/9 + 1/99
= 44 + 1/99 = 45/99 = 5/11
2 x [(3.6 x 0.48 x 2.50) / (0.12 x 0.09 x 0.5)]
= 2 x [(36 x 48 x 250) / (12 x 9 x 5)]
= 2 x 4 x 4 x 50 = 1600
