Question

Answer 1

Answer:

Raiba sowed 2/21 of his farm as watermelon

Step-by-step explanation:

Let w be the part that Raiba planted watermelon.

∵ there are only 3 varieties in his farm.

∴ $\frac{4}{7} + \frac{1}{3} + w = 1$

⇒ w = 1 - ($\frac{4}{7} + \frac{1}{3}$)

⇒ w = (21 - 12 - 7)/21    ...taking 21 as the LCM of denominator

⇒ w = 2/21
