Question

(3 + 1/(5/12 + 1/3)) + (2 + 1/(3 + 3/4)) - (1 + 1/(1 + 2/3))

Вычислите:

Answer 1

1/3=4/12

5/12+4/12=9/12

1/9/12=12/9

3=27/9 3+12/9=27/9+12/9=39/9=13/3

3=12/4 12/4+3/4=15/4

1/15/4=4/15

2=30/15 30/15+4/15=34/15

1=3/3 3/3+2/3=5/3

1/5/3=3/5

1=5/5 5/5+3/5=8/5

13/3=65/15 8/5=24/15

65/15+4/15+24/15=93/15= 31/5
