-5/9 - (-7/27)
Can someone help

Sagot :

Answer:

[tex]\frac{-8}{27}[/tex]

Step-by-step explanation:

[tex]\frac{-5}{9}[/tex] - [tex]\frac{-7}{27}[/tex]  Subtracting a negative is the same as adding a positive.  So I would change the form to addition.

[tex]\frac{-5}{9}[/tex] + [tex]\frac{7}{27}[/tex]  Now to add, we need a common denominator.  Let's us 27

[tex]\frac{-5}{9}[/tex] = [tex]\frac{-15}{27}[/tex]  We multiple the numerator and denominator (top and bottom) by 3 to make an equivalent fraction.

[tex]\frac{-15}{27}[/tex] + [tex]\frac{7}{27}[/tex]  the bottom number stays the same and we add the top numbers

-15 + 7 = -8

[tex]\frac{-8}{27}[/tex]

Answer: -8/27

Step-by-step explanation:

[tex]\displaystyle\\-\frac{5}{9} -(-\frac{7}{27} )=\\\\-\frac{5*3}{9*3} +\frac{7}{27} =\\\\\frac{-15}{27}+\frac{7}{27}=\\\\ \frac{-15+7}{27}=\\\\ \frac{-8}{27} =\\\\-\frac{8}{27}[/tex]
