Answer 2

To solve the expressions, we'll perform the arithmetic step by step:

1. 103/580 + 102/580 - (152/580 - 68/580):

To add and subtract fractions, the denominators must be the same. In this case, the denominators are already the same (580). So, we can directly add and subtract the numerators:

(103 + 102 - (152 - 68)) / 580

Now, perform the operations within parentheses:

(205 - 84) / 580

Now, subtract:

121 / 580

2. 619/925 - 586/925 + 53/925:

Again, the denominators are already the same (925), so we can directly add and subtract the numerators:

(619 - 586 + 53) / 925

Now, perform the operations:

(86) / 925

Now, both expressions have been simplified, and we get:

1. 103/580 + 102/580 - (152/580 - 68/580) = 121/580
2. 619/925 - 586/925 + 53/925 = 86/925
