7. Compare (> , = , <).

Analysis of the first column:

• 54 : 18 = 3, 48 : 12 = 4. Since 3 < 4, the sign is '<'.
• 7 * 13 = 91, 5 * 16 = 80. Since 91 > 80, the sign is '>'.
• 64 : 20 = 3.2, 88 : 4 = 22. Since 3.2 < 22, the sign is '<'.
• 25 * 3 = 75, 36 : 2 = 18. Since 75 > 18, the sign is '>'.
• 96 : 16 = 6, 98 : 14 = 7. Since 6 < 7, the sign is '<'.
• 17 * 5 = 85, 4 * 19 = 76. Since 85 > 76, the sign is '>'.
• 92 : 2 = 46, 86 : 2 = 43. Since 46 > 43, the sign is '>'.
• 5 * 12 = 60, 21 * 3 = 63. Since 60 < 63, the sign is '<'.
• 54 : 3 = 18, 72 : 4 = 18. Since 18 = 18, the sign is '='.

Analysis of the second column:

• 26 * 3 = 78, 39 * 2 = 78. Since 78 = 78, the sign is '='.
• 74 : 2 = 37, 58 : 2 = 29. Since 37 > 29, the sign is '>'.
• 18 * 4 = 72, 14 * 6 = 84. Since 72 < 84, the sign is '<'.
• 96 : 8 = 12, 78 : 6 = 13. Since 12 < 13, the sign is '<'.
• 15 * 5 = 75, 35 * 2 = 70. Since 75 > 70, the sign is '>'.
• 84 : 4 = 21, 63 : 3 = 21. Since 21 = 21, the sign is '='.
• 27 * 3 = 81, 18 * 5 = 90. Since 81 < 90, the sign is '<'.
• 72 : 4 = 18, 54 : 3 = 18. Since 18 = 18, the sign is '='.
• 56 : 4 = 14, 70 : 5 = 14. Since 14 = 14, the sign is '='.
