Answer 1

Ответ:

1)= 3 26/30+6 21/30=(3+6)+26/30+21/30=9 47/30=10 17/30

2)=(9+4)+32/84+66/84=13 98/84=14 14/84=14 1/6

3)=(8+7+12)+20/36+27/36+21/36=27 68/36=28 32/36=28 8/9

4)= (7-3)+(5/6-4/6)=4+1/6=4 1/6

5)=(8-6)+(25/60-21/60=2+ 4/60=2 4/60=2 1/15

6)=(11-5)+(33/36-28/36)=6+5/36=6 5/36

7)=(9-8)+(51/72-22/72)=1 +29/72=1 29/72

Answer 2

To solve the given expression, let's break it down step by step:

3 + 13/15 + 6 + 7/10 + 9 + 8/21 + 4 + 11/148 + 5/9 + 7 + 3/4 + 12 + 7/127 + 5/6 - 3 + 2/38 + 5/12 - 6 + 7/2011 + 11/12 - 5 + 7/99 + 17/24 - 8 + 11/36

Addition and Subtraction:

We can start by performing the addition and subtraction operations from left to right:

3 + 13/15 = 3.86667 3.86667 + 6 = 9.86667 9.86667 + 7/10 = 10.56667 10.56667 + 9 = 19.56667 19.56667 + 8/21 = 19.90476 19.90476 + 4 = 23.90476 23.90476 + 11/148 = 23.97973 23.97973 + 5/9 = 24.63407 24.63407 + 7 = 31.63407 31.63407 + 3/4 = 31.88407 31.88407 + 12 = 43.88407 43.88407 + 7/127 = 43.94567 43.94567 + 5/6 = 44.27833 44.27833 - 3 = 41.27833 41.27833 + 2/38 = 41.33158 41.33158 + 5/12 = 41.69158 41.69158 - 6 = 35.69158 35.69158 + 7/2011 = 35.69467 35.69467 + 11/12 = 36.56967 36.56967 - 5 = 31.56967 31.56967 + 7/99 = 31.64343 31.64343 + 17/24 = 32.34343 32.34343 - 8 = 24.34343 24.34343 + 11/36 = 24.63611

Therefore, the final result of the expression is approximately 24.63611.

Please note that the above calculations are rounded to five decimal places for simplicity.
