Question

-4/42+-3/7+-2/21
please help me guys​

Answer 1

Answer:

-13/21

Step-by-step explanation:

$\frac{ - 4}{42} + \frac{ - 3}{7} + \frac{ - 2}{21} \\ = \frac{( - 4) + 6 \times ( - 3) + 2 \times ( - 2)}{42} \\ = \frac{ - 4 - 18 - 4}{42} \\ = \frac{ - 26}{42} = \frac{ - 13}{21}$

Answer 2

Answer:

(-4/42)+(-3/7)+(-2/21)

=(-2/21)+(-3/7)+(-2/21)

=(-2/21 -3/7 -2/21)

=(-4/21 -3/7)

=(-4-9/21)

=(-13/21) Ans.

Hope this helps...
