See the entire simplification process below:

First, we must put the fractions over a common denominator (35 in this case) by multiplying each fraction by the appropriate form of $1$ :

$(5/5 xx -2/7) + (7/7 xx -2/5) ->$

$-10/35 + (-14/35)$

We can now add the numerators over a common denominator:

$(-10 + (-14))/35 ->$

$(-10 - 14)/35 ->$

$-24/35$

How do you simplify -2/7 + (-2/5)-2/7 + (-2/5)?
