б) 7 * 2\3+7*1\2+7*5\6=

Answer 1

А) (3\4+3\8+5\6)*24= 3/4*24/1+3/8*24/1+5/6*24/1= 18+9+20=47;//// б) 7 * 2\3+7*1\2+7*5\6= 7*(4/6+3/6+5/6)=7*2=14

Answer 2

А)
(3\4 + 3\8 + 5\6) * 24 = (18/24 + 9/24 + 20/24) * 24 = 47/24 * 24 = 47,

б)
7 * 2\3 + 7 * 1\2 + 7 * 5\6 = 7 * (2/3 + 1/2 + 5/6) = 7 * (4/6 + 3/6 + 5/6) = 7 * 12/6 = 7 * 2 = 14
