Answer:
a)Rice => 1/4
b) Vegetables => 1/4
Step-by-step explanation:
Lets say the farmers field was in a square shape. Now divide this square into 4 parts.
Now, each part is 1/4
So, half of his field is for wheat cultivation, i.e., 1/4 + 1/4 = 2/4 = 1/2
So, the other half is for rice and vegetables
2 vegetables have to be grown on the other half
So,
Fraction of field required for growing rice = 1/4
Fraction of field required for growing vegetables = 1/4
