16 20/21 * 28 3/7 - 4 13/25 + 8 2/47
(16*21+ 20)/21 * (28*7+ 3)/7 - (4*25+ 13)/25 + (8*47+ 2)/47
(16*21+ 20)/21 * (28*7+ 3)/7 - (4*25+ 13)/25 + (8*47+ 2)/47
356/21*199/7-113/25+378/47
(356*199)/(21*7)-113/25+378/47
(356*199)/(21*7)-113/25+378/47

485.45452598060500796063106093501, because
it is equal to
[(16+(20/21))*(28+(3/7))]+8+(2/47)-4-(13/25)
As a sanity check, to show that the answer is reasonable, 17*28=476, so it is in the same ballpark.
