= сорок шесть целых пять седьмых
Пошаговое объяснение:
10× 4/7 = 10·4/7 = 40/7 = 5·7 + 5/7 = 5 5/7
5 5/7 - 29 = 5 + 5/7 - 29 = 5/7 - 24 = 5/7 - 24·7/7 = 5/7 - 168/7 = 5 - 168/7 = - 163/7 = - 23·7 + 2/7 = -23 2/7
-23 2/7 - 1/14 = - 23 - 2/7 - 1/14 = -23 - 2 · 2/7 · 2 - 1 · 1/14 · 1 = -23 - 4 14 - 1/14 = - 23 - 4 + 1/14 = - 23 - 5/14 = -23 5/14
-23 5/14 ÷ 1 2 = - 5 + 23·14/14 ÷ 1 2 = - 327/14 ÷ 1 2 = - 327/14 × 2/1 = - 327·2/14·1 = - 654/14 = - 327 · 2/7 · 2 = - - 327/7 = - 46·7 + 5/7 = -46 5/7
