Пошаговое объяснение:

a) = 0,8*(5,19+0,81) = 0,8 * 6 = 4,8

b) = 2,5*(9,2299+0,7701) = 1,5 * 10 = 15

c) = 99,977*(1 3/5 - 0,6) = 99,977*(1,6-0,6) = 99,977 * 1 = 99,977

d) = 77,77*(5/8 - 0,625) = 77,77*(0,625-0,625) = 77,77*0 = 0

e) = (5*0,2)*(9*1/9) = 1 * 1 = 1

f) = (1/25*50)*(5,5*0,2) = 2 * 1,1 = 2,2
