Answer:
[tex] \frac{1}{3} - \frac{1}{2} + \frac{2}{5} [/tex]
[tex] = \frac{10 - 15 + 2 \times 6}{30} [/tex]
[tex] = \frac{10 - 15 + 12}{30} [/tex]
[tex] = \frac{ - 5 + 12}{30} [/tex]
[tex] = \frac{7}{30} [/tex]
Answer:
[tex] \frac{1}{3} - \frac{1}{2} + \frac{2}{5} [/tex]
[tex] = \frac{10 - 15 + 2×6}{30} [/tex]
[tex] = \frac{10 - 15 + 12}{30} [/tex]
[tex] \frac{-5 +12}{30} [/tex]
= 7 /30
