Question
here are 25 trees on the Jackson’s property. Twenty percent of the trees are oak trees. Which equation can be used to find the number of oak trees on the property?
StartFraction 25 divided by 1 Over 20 divided by 1 EndFraction = StartFraction 25 Over 20 EndFraction
StartFraction 100 times 5 Over 20 times 5 EndFraction = StartFraction 500 Over 100 EndFraction
StartFraction 20 times 4 Over 25 times 4 EndFraction = StartFraction 80 Over 100 EndFraction
StartFraction 20 divided by 4 Over 100 divided by 4 EndFraction = StartFraction 5 Over 25 EndFraction
StartFraction 25 divided by 1 Over 20 divided by 1 EndFraction = StartFraction 25 Over 20 EndFraction
StartFraction 100 times 5 Over 20 times 5 EndFraction = StartFraction 500 Over 100 EndFraction
StartFraction 20 times 4 Over 25 times 4 EndFraction = StartFraction 80 Over 100 EndFraction
StartFraction 20 divided by 4 Over 100 divided by 4 EndFraction = StartFraction 5 Over 25 EndFraction

To find the number of oak trees on the Jackson's property, you can use the information that 20% of the trees are oak trees.
1. First, we calculate 20% of 25 trees:
\[
0.2 \times 25 = 5
\]
So, there are 5 oak trees.
Among the equations you've provided, the one that directly calculates this is:
\[
\frac{25}{1 \div 0.2} = \frac{25}{5}
\]
However, that specific form isn't listed among the options.
Instead, let’s evaluate which option resembles the correct principle of calculating 20%:
1. **StartFraction 25 divided by 1 Over 20 divided by 1 EndFraction = StartFraction 25 Over 20 EndFraction**
- This represents \(25 \div \left(\frac{1}{5}\right)\) which is not correct.
2. **StartFraction 100 times 5 Over 20 times 5 EndFraction = StartFraction 500 Over 100 EndFraction**
- This simplifies correctly but does not help find the number of trees.
3. **StartFraction 20 times 4 Over 25 times 4 EndFraction = StartFraction 80 Over 100 EndFraction**
- The left side simplifies, but it does not relate directly to finding the number of oak trees.
4. **StartFraction 20 divided by 4 Over 100 divided by 4 EndFraction = StartFraction 5 Over 25 EndFraction**
- This simplifies \(5/25\) which does represent a proportion but not the calculation of the number of oak trees.
None of the equations accurately find the number of oak trees directly. The best way to express the calculation of finding the number of oak trees would simply be \(0.2 \times 25\) or \( \frac{20}{100} \times 25 \).
However, if you had to pick the most relevant, option 4 does seem to relate to the final ratio of \(5\) trees related to the total.
In conclusion, the direct equation to find the number of oak trees from the information given should simply be:
\[
0.2 \times 25 = 5
\]
There seems to be confusion with the provided options, as none of them yield an exact calculation for the number of oak trees directly.
