Question

Raul plowed 8/9 of the field. Then he planted blackberries on 1/7 of the plowed part. What fraction of the whole field is planted with blackberries?

Answer 1

Given that:

- Raul plowed this portion of the field:

`(8)/(9)`

- And he planted blackberries on this portion of the plowed part:

`(1)/(7)`

You need to set up the following Multiplication of fractions, in order to find the fraction of the whole field that is planted with blackberries:

`(8)/(9)\cdot(1)/(7)`

To solve it, you need to multiply the numerators and multiply the denominators:

`=(8\cdot1)/(9\cdot7)=(8)/(63)`

Hence, the answer is:

`\frac{8}{63\text{ }}\text{ of the whole field is planted with blackberries.}`
