nyatakan ke bentuk yang paling sederhana b. 4/5t+3/5s-1/3t-1/2s

[tex] \frac{4}{5} t + \frac{3}{5} s - \frac{1}{3} t - \frac{1}{2} s \\ = \frac{4}{5} t - \frac{1}{3} t + \frac{3}{5} s - \frac{1}{2} s \\ = \frac{3 \times 4 - 5 }{15} t + \frac{2 \times 3 - 5}{10} s\\ = \frac{12 - 5}{15} t + \frac{6 - 5}{10} s \\ = \frac{7}{15} t + \frac{1}{10} s\\=\frac{7}{15} t + \frac{s}{10}[/tex]
Maaf Kalau Salah

4/5 t - 1/3 t + 3/5 s- 1/2s
= (12-5)/15 t + (6-5)/10 s
= 7/15 t + 1/10 s
