Answer 1

$\huge \mathfrak \pink{Answer}$

There are 2 ways to solve the above equation:

1st Way: If we need the desired output in decimal point then, by using the BODMAS method will divide the values:

3/5 = 0.6 and 2/7 = 0.286(approx)

So the output of the above equation = 0.6 + 0.286 = 0.886

2nd Way: If we need the desired output in fraction format then, will find the LCM of both denominators 5 and 7

LCM of 5 and 7 = 35

So the equation 3/5 + 2/7 can be written as

= [(3*7)/35 + (2*5)/35]

= [21/35 +10/35]

So the output of above equation - 31/35

Answer 2

$\frac{2}{7} - \frac{3}{5} \cancel{ = } \frac{3}{5} - \frac{2}{7} \\ \frac{10 - 21}{35} \cancel{ = } \frac{21 - 10}{35} \\ \frac{ - 11}{35} \cancel{ = } \frac{11}{35} \\ \\ there \: is \\ \: diff \: of \: \frac{22}{35} in \: them$
