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!!

What is 25% of 24?<br> What is 15% of 60?<br> 9 is what percent of 72

JulsSmile [24]

Answer:

6.48

Step-by-step explanation:

this is the easiest way to solve for percentage:

$\frac{part}{whole} =\frac{part}{whole}$ Where all the percents (except 100) would go in part

and the whole number would go in whole

$\frac{25}{100} =\frac{?}{24}$ Then multiply 24 × 25 ÷ 100 = 6

$\frac{15}{100} =\frac{?}{60}$ Multiply 60 by 25 then divided by 100 = 9

Then for the last one 9 is what percent of 72

all we have to do is multiply 9 and then convert 72 into a decimal (0.72)

Then 9 × 0.72 = 6.48
