Answer:
a) [tex] \frac{11}{15} [/tex]
b) [tex] \frac{1}{18} [/tex]
Step-by-step explanation:
[tex]a) \: \frac{2}{5} + \frac{1}{3} [/tex]
[tex] \frac{2}{5} \times \frac{3}{3} + \frac{1}{3} \times \frac{5}{5} [/tex]
[tex] \frac{2 \times 3}{5 \times 3} + \frac{1 \times 5}{3 \times 5} [/tex]
[tex] \frac{6}{15} + \frac{5}{15} [/tex]
[tex] \frac{6 + 5}{15} [/tex]
[tex] \frac{11}{15} [/tex]
[tex]b) \: \frac{5}{9} - \frac{1}{2} [/tex]
[tex] \frac{5}{9} \times \frac{2}{3} - \frac{1}{2} \times \frac{9}{9} [/tex]
[tex] \frac{5 \times 2}{9 \times 2} - \frac{1 \times 9}{2 \times 9} [/tex]
[tex] \frac{10}{18} - \frac{9}{18} [/tex]
[tex] \frac{10 - 9}{18} [/tex]
[tex] \frac{1}{18} [/tex]
