the ratio of pine trees to elm trees in a park is 7:11. How many pine trees are there in the park if there are 68 more elm trees

Hitman42 [59]

Answer:

The number of pine tree is 119 and the number of elm tree is 187.

Step-by-step explanation:

The ratio of pine trees to elm trees in a park is 7:11

Let us assume that the number of pine tree is 7x and the number of elm tree is 11x.

It is also given that, there are 68 more elm trees as compared to the pine trees.

i.e $11x=7x+68$

$\Rightarrow 11x-7x=68$

$\Rightarrow 4x=68$

$\Rightarrow x=17$

Hence, the number of pine tree = $7x=7\times 17=119$ and the number of elm tree = $11x=11\times 17=187$
