Г) (3 1/2 - 2 3/4) * (1 1/6 - 5/12) = 9/16
1) 3 1/2 - 2 3/4 = 3 2/4 - 2 3/4 = 2 6/4 - 2 3/4 = 3/4
2) 1 1/6 - 5/12 = 7/6 - 5/12 = 14/12 - 5/12 = 9/12 = 3/4
3) 3/4 * 3/4 = 9/16
д) (6 7/12 - 5 11/15) * (1 3/17 - 10/17) = 1/2
1) 6 7/12 - 5 11/15 = 6 35/60 - 5 44/60 = 5 95/60 - 5 44/60 = 51/60
2) 1 3/17 - 10/17 = 20/17 - 10/17 = 10/17
3) 51/60 * 10/17 = (3*1)/(6*1) = 3/6 = 1/2
