Final answer:
Juan Pablo has 3.5 acres of land left to mow.
Step-by-step explanation:
To find out how many acres of land Juan Pablo has left to mow, we need to subtract the area he has already mowed from the total area of land he owns.
Juan Pablo owns 5 14/20 acres of land, which can be written as a mixed number of 5 7/10 acres. We can convert the mixed number to an improper fraction by multiplying the whole number by the denominator and adding the numerator. This gives us 57/10 acres.
Juan Pablo has already mowed 2 1/4 acres of land, which is equivalent to 2.25 acres.
To find the remaining acres of land, we subtract the acres mowed from the total acres owned:
57/10 - 2.25 = 57/10 - 22/10 = 35/10 = 3.5 acres.
