Answer:
A) She should buy the
Step-by-step explanation:
<u>Part A:</u>
For question A, we find the areas of both plots and see which one is greater.
For the first one, we do 3/8 * 2/3
The area of the first plot is 1/4 square miles
For the second one, we do 2/5 * 2/5
The area of the second plot is 4/25 square miles
We have 1/4 and 4/25.
To see which one is bigger, we make them have the same denominator, also known as the LCM (Least Common Multiple).
LCM(4,25) = 100
Now we make 1/4 have a denominator of 100
4 times what is 100?
25, so the numerator is 25 and the denominator is 100.
We get: 25/100
Now we make 4/25 have a denominator of 100
25 times what is 100?
4, so the numerator is 4 * 4 = 16 and the denominator is 100.
We get: 16/100
Now we can see which is bigger:
25/100 or 16/100
25/100 is bigger
Therefore, Miguel's mother should buy the plot with dimensions 3/8 and 2/3.
<u>Part B</u>
For part B, I'm not sure which plot of land she is going to pay for, so I will answer both.
We answered this in Part A already.
The 3/8 and 2/3 plot was 1/4 square miles and the 2/5 by 2/5 plot was 4/25 square miles.
Plot 1:
1/4 square miles
It said that it costs $750,000 for a square mile
This plot is 1/4 square miles, so we do
The cost for plot 1 is $187,500
Plot 2:
4/25 square miles
It said that it costs $750,000 for a square mile
This plot is 4/25 square miles, so we do
The cost for plot 1 is $120,000
So for the 3/8 by 2/3 plot, it cost $187,500 and for the 2/5 by 2/5 plot costs $120,000
