答案

0.79+0.79×99＝ 1÷5+1÷5＝ 0.89×101-0.89＝ 2－0.64－0.36=
37.2×99＋37.2= 25×4÷0.25×4= 0.9×7+10.7
9÷5－1.9÷5﹦ 6.8-2.4÷3= 0.6÷0.3+0.5= 1.9+5.1÷51= 1.8÷0.9×0.5= 12-0.05×4= 1×0.01÷0.1= 7.2-1.2+6.7=
1.01×99＝ 420÷35＝ 25×12＝ 135÷0.5= 45× 35 = 9×718 = 23 × 910 = 425 ×100= 18×16 = 411 × 114 = 17× 916 = 5 × 34 = 38 × 12 = 38 ×12= 13 ×0= 38 × 12 = 38 ×12= 13 ×0= 4 × 25 = 56 ×12= 712 × 314 = 45× 35 = 9×718 = 23 × 910 = 425 ×100= 18×16 = 411 × 114 = 17× 916 = 5 × 34 = 14 × 25 = 56 ×12= 712 × 314 =485 - ( 6×4 + 32 ) 1000 - ( 500 + 499 + 1 ) 3651 ×(52 +500 - 100 ) 123×（4 ×5-14）
