Question

Вычислите2 целых 1/3+4целых1/10: (2целых7/15-5/12)*5/6

Answer 1

7/3 + 41/10:(37/15-5/12)*5/6 =  7/3 + 41/10:(148/60-25/60)*5/6 = 7/3 + 41/10 : 123/60 * 5/6 = 7/3 + 41/10 * 60/123 * 5/6 = 7/3 + 2*5/6 = 7/3+10/6 = 14/6+10/6 = 24/6 = 4

Ответ: 4

Answer 2

2 1/3+4 1/10: (2 7/15-5/12)*5/6=4
1) 2 7/15-5/12=37/15-5/12=37*4/60-5*5/60=148/60-25/60=123/60=2 3/60= 2 1/20
2) 4 1/10:2 1/20= 41/10:41/20=41*20/10*41=20/10=2
3) 2*5/6=10/6=1 4/6=1 2/3
4) 2 1/3+1 2/3=3 3/3=4
