1/3=1×18/18×3=18/54
4/9=4×6/9×6=24/54
5/6=5×9/6×9=45/54
5/18=5×3/18×3=15/54
8/27=8×2/27×2=16/54
2+7/16-1+3/8=2+7/16-1+6/16=1+1/16
1/2 = 1*3 / 2*3 = 3/6 = 2/6 + 1/6 = 1/3 + 1/6
1/4 = 1*5 / 4*5 = 5/20 = 4/20 + 1/20 = 1/5 + 1/20
1/6 = 1*7 / 6*7 = 7/42 = 6/42 + 1/42 = 1/7 + 1/42
1/8 = 1*9 / 8*9 = 9/72 = 8/72 + 1/72 = 1/9 + 1/72
54÷6=9. То есть меньше 54 в 6 раз будет 9
