4 4/9 * 1 1/32 * 1 1/5 - (2 11/14 - 2 2/35) * 4 2/3 = 2 1/10
выражением:
= 40/9 * 33/32 * 6/5 - (39/14 - 72/35) * 14/3 =
= [(1 * 11 * 1) / (1 * 2 *1) ] - ( 39/14 * 14/3 - 72/35 * 14/3 ) =
= 5 1/2 - (13 - 48/5 ) = 5 1/2 - ( 13 - 9 3/5 ) =
= 5 1/2 - 3 2/5 = 5 5/10 - 3 4/10 = 2 1/10
по действиям:
1) 2 11/14 - 2 2/35 = 2 55/70 - 2 4/70 = 51/70
2) 4 4/9 * 1 1/32 = 40/9 * 33/32 = (5*11)/(3*4)=55/12 = 4 7/12
3) 4 7/12 * 1 1/5 = 55/12 * 6/5 = 11/2 = 5 1/2
4) 51/70 * 4 2/3 = 51/70 * 14/3 = (17*1)/(5*1)= 3 2/5
5) 5 1/2 - 3 2/5 = 5 5/10 - 3 4/10 = 2 1/10
