Answer 1

(1) <

(2) <

(3) =

(4) <

Explanation:

`By \ applying \ the \ rule \ of \ BODMAS \ (i.e. \ Bracket, \ of, \ Division,\ Multiplication, \ Addition,`
`\ and \ Subtraction).`

(1)

5 + 8 - 2 -7 = 13 × 10 - 17

13 - 9 = 130 - 17

4 < 113

(2)

22 × 3 - 42 + 20 = 72 -2 + 13 - 16

66 - 22 = 72 + 11 - 16

44 < 67

(3)

12 + 13 - 4 × 5 = 4 × 3 - 7

12 + 13 - 20 = 12 - 7

5 = 5

(4)

45 - 10 × 2 + 17 = 8 ×9 - 5 + 30

45 - 20 + 17 = 72 + 25

42 < 97
