1) = 25 - 26 = ( - 1 ) 2) = 19 - 48 = ( - 29 ) 3) = 60.4 - 70.4 = ( - 10 ) 4) 1) 3 1\3 + 1 2\3 = 4 3\3 = 5 2) 2 3\5 + 2 2\5 = 4 5\5 = 5 3) 5 + 3 2\15 = 8 2\15 4) 5 - 8 2\15 = ( - 3 2\15 ) ( ответ )
2-15+23-11=-1 -31+14+5-17=-29 24.8+35.6-14.8-55.6=-10 3 1/3 - 2 3/5+1 2/3 - 2 2/5 - 3 2/15 = 3 5/15 - 2 9/15+1 10/15 - 2 6/15 - 3 2/15= =- 3 2/15
