Question

7/18-m=1/12
9 целых 5/6 (m - 1 целая 1/4) =3 целых 3/7

Answer 1

7/18 - м = 1/12,

м = 7/18 - 1/12,

м = 14/36 - 3/36,

м = 11/36,

9 5/6 * (м - 1 1/4) = 3 3/7,

м - 1 1/4 = 3 3/7 : 9 5/6,

м - 1 1/4 = 24/7 : 59/6,

м - 1 1/4 = 24/7 * 6/59,

м - 1 1/4 = 144/413,

м = 144/413 + 1 1/4,

м = 144/413 + 5/4,

м = 576/1652 + 2065/1652,

м = 2641/1652,

м = 1 989/1652
