Answer 1

#3,375 + 4 1/6 - 2 2/3 = 3,375 + 25/6 - 8/3= 3,375 + 25/6 - 16/6= 3,375 + 9/6= 3,375 + 1,5 = 4, 875
#4,5 + 6 3/4 - (12 - 5 3/8) = 45/10 + 27/4 - ( 11 8/8 - 5 3/8 ) = 45/10 + 27/4 - 6 5/8 = 45/10 + 27/4 - 53/8 = 180/40+ 270/40 - 265/40 = 185/40 = 4 25/40 = 4 5/8
#4 3/8 * 3 * 1 1/7 = 35/8 * 3 * 8/7 = 105/7 = 15
#1 13/15 : 1 1/5 : 14 = 28/15 : 6/5 : 14 = 28/15 * 5/6 * 1/14 = 2/18 = 1/9

#1 2/3 + 2 3/4 + 3 4/5 * (8 2/5 - 7 3/20) = 5/3 + 11/4 + 19/5 * (42/5 - 143/20) = 5/3 + 11/4 + 19/5 * ( 168/20 - 143/20 ) = 5/3 + 11/4 + 19/5 * 25/20 = 5/3 + 11/4 + 15/4 = 20/12 + 33/12 + 45/12 =98/12=49/6= 8 1/6 
# 2 3/5 * 6 1/4 - 3 1/4 : 3 5/7 + 0,625 = 13/5 * 25/4 - 13/4 : 26/7 + 5/8 = 65/4 - 13/4 * 7/26 + 5/8 = 65/4 - 7/8 + 5/8 = 130/8 - 7/8 + 5/8 = 128/8 = 16
