А)4/15*2+2/3:5= 8/15 + 2/3 * 1/5 = 8/15 + 2/15 = 10/15 = 2/3
Б)7/8:3-1/24*5= 7/8 * 1/3 - 5/24 = 7/24 - 5/24 = 2/24 = 1/12
В)3/20*3-3/10:2= 9/20 - 3/10 * 1/2 = 9/20 - 3/20 = 6/20 = 3/10
Г)1/18*7+5/6:3= 7/18 + 5/6 * 1/3 = 7/18 + 5/18 = 12/18 = 2/3
Д)4/45*9-2/3:5= 4/5 - 2/3 * 1/5 = 4/5 - 2/15 = 12/15 - 2/15 = 10/15 = 2/3
Е)3/8:6+5/32*4= 3/8 * 1/6 + 5/8 = 3/48 + 5/8 = 1/16 + 5/8 = 1/16 + 10/16 = 11/16
