Answer:
2/3 < 5/7 < 3/4 < 5/6
Explanation:
Method 1 : Converting to decimals
2/3 = 0.66
5/7 = 0.71
3/4 = 0.75
5/6 = 0.83
0.66 < 0.71 < 0.75 < 0.83
Method 2 : Converting to fractions with same denominators
(2x28) / (3x28) = 56 / 84
(5x12)/(7x12) = 60/84
(3x21)/(4x21) = 63/84
(5x14)/(6x14) = 70/84
56 / 84 < 60/84 < 63/84 < 70/84
