Question

1.kebun dengan luas 1200m,akan ditanam kacang 2 per 3 bagian,& ditanami cabe 1 per 4 bagian,jika sisanya ditanami jagung,maka luas yg ditanam jagung?

Answer 1

2/3 + 1/4 + jagung = 1
8/12 + 3/12 + jagung = 12/12
11/12 + jagung = 12/12
jagung = 12/12 - 11/12
jagung = 1/12 bagian

Luas kebun yang ditanami jagung
= 1/12 × 1.200
= 100 m^2

Answer 2

2/3 x 1200 = 800
1/4 x 1200 = 300
1200-800-300 = 100 m^2
