1/3+2/7×14/36-1/9:4/3

= 1/3 + (2/7 × 14/36) - (1/9 : 4/3).
= 1/3 + 28/252 - (1/9 × 3/4).
= 84/252 + 28/252 - 3/36.
= 112/252 - 21/252.
= 91/252.
= 13/36.
maaf kalau salah

1/3+(2/7×14/36)-(1/9÷4/3)
1/3+2/18-(1/9×3/4)
1/3+2/18-3/36
disamakan penyebutnya
12/36+4/36-3/36
16/36-3/36
13/36

maaf kalau salah
senang bisa membantu
