Ada soal matematika seperti ini:

Luas taman pak Ahmad 300m². 1/3 bagian ditanami bunga mawar, 1/4 bagian ditanami bunga melati, 1/5 bagian ditanami bunga anyelir, dan sisanya dibuat kolam. Luas kolam adalah:

Terus jawabannya: 1-(1/3+1/4+1/5) = 1-(20/60+15/60+12/60)
= 1- 47/60 = 13/60
Luas kolam 13/60 x 300m² = 65 m²

Nah, yang mau aku tanyain, itu (1-) dan (1-47/60 = 13/60) darimana?

Makasih
