Ling owns two-third acre of land. She plants beetroot on four-fifths of the land. How many acre of the land is the beetroot planted on?

8/15 acres

Step-by-step explanation:

There are 2/3 acres of land to plant on.

Ling plants on 4/5 of this land.

To find the number of acres she planted on, multiply both numbers.

= 2/3 * 4/5

= 8/15 acres

As the fraction cannot be taken lower, the amount of acres planted on is 8/15 acres.
