504 is 500 to nearest 10
548 is 550 to nearest 10
541 is 500 to nearest 100
552 to nearest 100 is 600
545 is 550 to nearest 10
Step-by-step explanation:
Let the size of their father's land be x.
The first born received x/4
The second, third and fourth born each received 1/6 * (x - x/4) = 3x/24 = x/8
The portion received by the last born = x - (x/4 + 3*x/8) = x - (x/4 + 3x/8) = x - (5x/8) = 3x/8
3x/8 = 3hectares
3x = 24
x = 8.
. : The initial size of the parcel land was 8 hectares.
The square root of 9764 should be 98.813. I had to round up though
