Answer 2

Let's start by simplifying the expressions within the parentheses and the division symbol:

(7 3/8 - 4 1/12) * 8/25 + (3 1/5 + 4 2/15) : 2 8/25

= (59/8 - 49/12) * 8/25 + (16/5 + 62/15) : 18/25 (converting mixed numbers to improper fractions)

= (177/24 - 98/24) * 8/25 + (48/15 + 124/15) : 18/25 (finding a common denominator for the fractions in the first term)

= 79/24 * 8/25 + 172/15 : 18/25 (simplifying the first term)

= 79/75 + (172/15 * 25/18) (multiplying by the reciprocal of the division in the second term)

= 79/75 + 215/6

= (796 + 21575)/(75*6)

= 16589/225

= 73.96 (rounded to two decimal places)

Therefore, the final answer is approximately 73.96.
