Question

There are 200 trees in garden . if 1/5 are plum trees and 2/5 are orange trees, then how many apple trees are there?

Answer 1

Step-by-step explanation:

trees =1/5+2/5

=3/5

=2/5

Answer 2

Given,

The total number of trees in a garden = 200

The fraction of plum trees among total trees = $\frac{1}{5}$

The fraction of orange trees among total trees = $\frac{2}{5}$

To Find,

The number of apple trees in the garden.

Solution,

• There are three types of trees in the garden, plum, orange, and apple.  The total number of trees is 200.
• The fraction of plum trees and orange trees among total trees are given.

∴The fraction of apple trees in the garden = $1- (fraction of plum trees + fraction of orange trees)$

⇒ $1-(\frac{1}{5} + \frac{2}{5} )$

⇒$1-(\frac{1+2}{5})$

⇒$1- \frac{3}{5}$

⇒$\frac{5-3}{5}$

⇒$\frac{2}{5}$

The number of apple trees in the garden = $(total number of trees)(fraction of apple trees)$

⇒$200(\frac{2}{5} )$

⇒80

Henceforth, the number of apple trees in the garden is 80.
