Question

помогите пожалуйста номер 993 (2,4,6)

Answer 1

2) (3/8 - 1/9) + 25/36 = (27/72 - 8/72) + 50/36 = (27 - 8 + 50)/72 = 69/72 = 23/24

4) (7/8 -13/20) + 9/10 =( 35/40 - 23/40) + 36/40 = (35 - 26 + 36)/40 = 45/40 = 9/8

6) (3/4 - 8/15) +17/20 = (45/60 - 32/60) + 51/60 = (45 - 32 + 51)/60 = 64/60 = 16/15
