231/2+18,26-25,7×2,6

[tex] \frac{231}{2} + \frac{1826}{100} - ( \frac{257}{10} \times \frac{26}{10} ) = \\ \frac{231}{2} + \frac{1826}{100} - \frac{3341}{50} = \\ \frac{11550 + 1826 - 6682}{100} = \\ \frac{6694}{100} = 66 \frac{94}{100} [/tex]
maaf kalo salah

231/2 + 18,26 - 25,7 × 2,6
= 115,5 + 18,26 - 66,82
= 233,76 - 66,82
= 166,94
