ANSWER:
[tex] \large\color{green}{ \tt{A. 1 / 10}}[/tex]
Solution Steps:
Least common multiple of 5 and 10 is 10. Convert 1/5 and 1/10 to fractions with denominator 10.
[tex]( \frac{2}{10} - \frac{1}{10} ) \times 3^{2} - \frac{4}{5} [/tex]
Since 2/10 and 1/10 have the same denominator, subtract them by subtracting their numerators.
[tex] \frac{2 - 1}{10} \times 3^{2} - \frac{4}{5} [/tex]
Subtract 1 from 2 to get 1.
[tex] \frac{1}{10} \times 3^{2} - \frac{4}{5} [/tex]
Calculate 3 to the power of 2 and get 9.
[tex] \frac{1}{10} \times 9 - \frac{4}{5} [/tex]
Multiply 1/10 and 9 to get 9/10.
[tex] \frac{9}{10} - \frac{4}{5} [/tex]
Least common multiple of 10 and 5 is 10. Convert 9/10 and 4/5 to fractions with denominator 10.
[tex] \frac{9}{10} - \frac{8}{10} [/tex]
Since 9/10 and 8/10 have the same denominator, subtract them by subtracting their numerators.
[tex] \frac{9 - 8}{10} [/tex]
Subtract 8 from 9 to get 1.
[tex] \large\color{green}\frac{1}{10} [/tex]
