Answer 1

Answer:

7/5+5/7

= 49+25/35

= 74/35

And in decimal,

74/35

= 2.114

Answer 2

$\dfrac{7}{5}+\dfrac{5}{7}=2\dfrac{4}{35}$

Tips:

We must know that the LCM of two or more Prime Numbers can be found by their product itself.

Step-by-step explanation:

Here, 5 and 7 are Prime Numbers and thus their LCM = 5 × 7 = 35.

Now, $\dfrac{7}{5}+\dfrac{5}{7}$

$=\dfrac{7\times 7+5\times 5}{35}$

$=\dfrac{49+25}{35}$

$=\dfrac{74}{35}$

$=2\dfrac{4}{35}$
