Answer 1

$( \frac{ \frac{2519}{100} }{26} + 0.47) - \frac{ \frac{77}{4} }{52} = ( \frac{2519}{2600} + \frac{47}{100} ) - \frac{77}{208} = \frac{3741}{2600} - \frac{77}{208} = \frac{5557}{5200} = 1 \frac{357}{5200}$

Answer 2

(25.19/26+4.7/10)-19.25/52 = (25.19/26-19.25/52) + 4.7/10 = 25.38/52 - 19.25/52 + 4.7/10 = 6.13/52 + 4.7/10 = 6.1/4 + 4 7/10 = 6.10/40 + 4.28/40 = 10.38/40 = 10.19/20
