Step 1: Simplify the division operation inside the parentheses: 5.8/9 = 0.6444444444444445 1.17/36 = 0.0325 1.1/4 = 0.275

The expression becomes: (0.6444444444444445 : 0.0325 + 0.275)*5/21

Step 2: Simplify the division operation: 0.6444444444444445 : 0.0325 = 19.7948717948718

The expression becomes: (19.7948717948718 + 0.275)*5/21

Step 3: Perform the addition operation inside the parentheses: 19.7948717948718 + 0.275 = 20.0708717948718

The expression becomes: 20.0708717948718*5/21

Step 4: Perform the multiplication and division operations: 20.0708717948718*5 = 100.354358974359 100.354358974359/21 = 4.77925428354

Therefore, the value of the expression (5.8/9:1.17/36+1.1/4)*5/21 is approximately 4.77925428354.
