please help me. -1/15 + (-3/5)

Sagot :

Answer:

[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

-1/5 + (-3/5)

Least common multiple of 15 and 5 is 15. Convert [tex]-\frac{1}{15}[/tex] and [tex]\frac{3}{5}[/tex] to fraction with a denominator of 15.

[tex]-\frac{1}{15}[/tex] [tex]-\frac{9}{15}[/tex]

Since [tex]-\frac{1}{15}[/tex]  and [tex]\frac{9}{15}[/tex] have the same denominator, subtract them by subtracting the numerators.

[tex]\frac{-1-9}{15}[/tex]

Subtract 9 from -1 to get -10

[tex]\frac{-10}{15}[/tex]

Reduce the fraction [tex]\frac{-10}{15}[/tex] to lowest terms

[tex]-\frac{2}{3}[/tex]
