b.) tomat
360-72-63-90-108 = 27 drajat
rumus :
27/360 x 400 = 30 kwintal
.
.
.c) 108/360 x 100persen = 30 persen
d.) 72 /360 x 100 persen = 20 persen

Kedelai = 63/360 x 400 = 70 kuintal
Tomat = 360-63-90-72-108 = 27
          = 27/360 x 400 = 30 kuintal

Presentase hasil panen kentang = 108/360 x 100 = 30%
Presentase hasil panen jagung = 72/360 x 100 = 20%
