In this exercise, we need to solve the basic arithmetic operations on each side of the brackets and then determine the correct relational symbol: greater than (>), less than (<), or equal to (=).
Let's approach each problem step-by-step:
3 + 5 [] 4 + 6
Calculate both sides:
Left side: 3 + 5 = 8
Right side: 4 + 6 = 10
Conclusion: 8 < 10 , so the correct symbol is < .
7 + 8 [] 9 + 3
Calculate both sides:
Left side: 7 + 8 = 15
Right side: 9 + 3 = 12
Conclusion: 12"> 15 > 12 , so the correct symbol is "> > .
4 + 3 [] 4 \times 3
Calculate both sides:
Left side: 4 + 3 = 7
Right side: 4 × 3 = 12
Conclusion: 7 < 12 , so the correct symbol is < .
21 + 5 [] 20 + 6
Calculate both sides:
Left side: 21 + 5 = 26
Right side: 20 + 6 = 26
Conclusion: 26 = 26 , so the correct symbol is = .
30 + 40 [] 20 + 60
Calculate both sides:
Left side: 30 + 40 = 70
Right side: 20 + 60 = 80
Conclusion: 70 < 80 , so the correct symbol is < .
5 + 5 + 5 [] 5 \times 3
Calculate both sides:
Left side: 5 + 5 + 5 = 15
Right side: 5 × 3 = 15
Conclusion: 15 = 15 , so the correct symbol is = .
Each side is evaluated separately and compared to determine the appropriate relationship symbol between the two expressions.
