Answer 2

Answer:

$\red { Value \: of \: \frac{41}{7} - \frac{21}{70}+\frac{(-3)}{35}} \green {= \frac{383}{70}}$

Step-by-step explanation:

$\red { Value \: of \: \frac{41}{7} - \frac{21}{70}+\frac{(-3)}{35}}$

$= \frac{41}{7} - \frac{21}{70}-\frac{3}{35}$

\* Find the LCM of 7, 70 and 35

7| 7, 70, 35

___________

5| 1 , 10, 5

___________

******* 2 , 1

$LCM (7,70,35) = 7\times 5 \times 2 = 70$

$= \frac{ 41\times 10 - 21 - 3\times 2}{70}$

$= \frac{ 410 - 21 - 6 }{70}\\=\frac{410-27}{70}\\= \frac{383}{70}$

Therefore.,

$\red { Value \: of \: \frac{41}{7} - \frac{21}{70}+\frac{(-3)}{35}} \green { =\frac{383}{70}}$
