in a wood there are 420 silver birch trees, 160 oak tees and 300 wild cherry trees. what is the percentage of the oak trees give

elena-14-01-66 [18.8K]

Answer:

18.2%

Step-by-step explanation:

The total number of trees in the wood = 420 + 160 + 300

= 880 trees

∴ The percentage of the oak trees = $\frac{160}{880} * \frac{100}{1}$

= $\frac{2 * 100}{11}$ %

= $\frac{200}{11}$ %

= 18.181818...%

In 1 decimal place = 18.2%

Hope this helps!!
