Answer:

0.362 hectares

Step-by-step explanation:

Just subtract 0.198 by 0.56. You're asking how?

    0.56

-    0.198

    0.362

0.56 will have 0 in it's digits so that it will be easier for us to subtract, 0.560 (The amount is still the same, we just added one 0 in the digit)

so,

    0.560              0-8 cannot be, so we will borrow 1 from 6 (560), now the 0

-    0.198               (560) will be 10 and the 6 will be 5. Now 10 - 8 = 2

    0.002

    0.560              5 - 9 cannot be (it became 5 because of the borrowing

-    0.198               process), now we will borrow again, 5 will borrow from 5

    0.062               (in 560) so it will become 460, and the 5 in the middle

                             will become 15. So 15 - 9 = 6

    0.560               So right now the number 5 (560) became number 4,

-    0.198                so it will be 4 - 1 = 3

    0.362

Therefore the part of Mrs. Padilla land that isn't alloted for the fishpond is 0.362 hectares.
