Question

(7/10-2/5)*(1/5+5/6):6 1/2 Всем Здрасти Можите Решить Этот Пример!

Answer 1

(7/10 - 2/5) * (1/5 + 5/6) : 6 1/2 = 31/650

1) 7/10 - 2/5 = 7/10 - 4/10 = 3/10
2) 1/5 + 5/6 = 6/30 + 25/30 = 31/30
3) 3/10 * 31/30 = (1*31)/(10 * 10) = 31/100
4) 31/100 : 6 1/2 = 31/100 : 13/2 = 31/100 * 2/13 = (31*1)/(50*13) = 31/650
