negative 3 over 7 plus 4 over 5

Sagot :

Answer: [tex]\frac{13}{35}[/tex]

Step-by-step explanation:

negative 3 over 7= [tex]-\frac{3}{7}[/tex]

Plus 4 over 5= [tex]\frac{4}{5}[/tex]

When adding fractions together, you should first change into a common denominator, then do the operation.

------------------------------------------------------------------------------------------------

[tex]-\frac{3}{7}[/tex] = [tex]-\frac{15}{35}[/tex]

[tex]\frac{4}{5}[/tex]= [tex]\frac{28}{35}[/tex]

 [tex]-\frac{3}{7}[/tex]+[tex]\frac{4}{5}[/tex]

=[tex]-\frac{15}{35}[/tex]+[tex]\frac{28}{35}[/tex]

=[tex]\frac{13}{35}[/tex]
