Answer 1

Ответ:

8/23-1/26=8*26-23*1/23*26-208-23/598=185/598

7/15-7/30=2*7-7/30=7/30

2/19-1/38=2*2-1/38=3/38

5/7-3/14=2*5-3/14=7/14=1/2

4/21-1/7=4-3*1/21=1/21

7/2+11/50=25*7+11/50=186/50=93/25

Answer 2

I'm assuming you want me to perform arithmetic operations on the given fractions.

Let's simplify each fraction first:

8/23 - 1/26 = (826 - 123) / (23*26) = 205/598

7/15 - 7/30 = (72 - 71) / (15*2) = 7/30

2/19 - 1/38 = (22 - 11) / (19*2) = 3/38

5/7 - 3/14 = (52 - 31) / (7*2) = 4/7

4/21 - 1/7 = (41 - 13) / (21*1) = 1/21

7/2 + 11/50 = (725 + 211) / (2*25) = 189/50

So, the final answer is:

205/598 + 7/30 + 3/38 + 4/7 + 1/21 + 189/50 = 7933/5970

Therefore, the result of the arithmetic operations on the given fractions is 7933/5970.
