To subtract two fractions we can use the following:
[tex]\frac{a}{b}-\frac{c}{d}=\frac{(a\cdot d)-(b\cdot c)}{b\cdot d}[/tex]So 5/6 - 5/9 is equal to:
[tex]\frac{5}{6}-\frac{5}{9}=\frac{(5\cdot9)-(6\cdot5)}{6\cdot9}=\frac{45-30}{54}=\frac{15}{54}[/tex]Finally, we can simplify the fraction dividing the numerator and denominator by 3, as:
[tex]\frac{15}{54}=\frac{15/3}{54/3}=\frac{5}{18}[/tex]So, the answer is 5/18
Answer: 5/18
