Question

Математика: По 2 целых 2/3: 2 целых + (4/15+2/5): (3 целых 1/3*3/5)

SerStroka · Answer

2 2/3 : 2 + (4/15 + 2/5) : (3 1/3 * 3/5) = 1 2/3
1) 4/15 + 2/5 = 4/15 + 6/15 = 10/15 = 2/3
2) 3 1/3 * 3/5 = 10/3 * 3/5 = 10/5 = 2
3) 2 2/3 : 2 = 8/3 : 2 = 8/3 * 1/2 = 4/3 = 1 1/3
4) 2/3 : 2 = 2/3 * 1/2 = 1/3
5) 1 1/3 + 1/3 = 1 2/3
