Найдите по формуле A=m-6 1/2

а) При m = 6 3/4, А = 6 3/4 - 6 1/2 = 6 3/4 - 6 2/4 = 1/4;
при m = 8 7/8, А = 8 7/8 - 6 1/2 = 8 7/8 - 6 4/8 = 2 3/8,
при m = 11, А = 11 - 6 1/2 = 10 2/2 - 6 1/2 = 4 1/2;
б) при А = 6 3/4, 6 3/4 = m - 6 1/2 => m = 6 3/4 + 6 1/2 = 6 3/4 + 6 2/4 = 12 5/4 = 13 1/4,
при А = 3 5/8, то 3 5/8 = m - 6 1/2 => m = 3 5/8 + 6 1/2 = 3 5/8 + 6 4/8 = 9 9/8 = 10 1/8,
при А = 0, то 0 = m - 6 1/2 => m = 6 1/2.
