Answer 2

(1)

Given, Mr. Dacwag had $\dfrac{3}{4}$ hectare of land.

He gave $\dfrac{1}{3}$ of hectare to his son.

Then the mathematical expression of the share of his remaining children

= $\dfrac{3}{4}-\dfrac{1}{3}$ hectare

Thus tge required share of his remaining children

= $\dfrac{3}{4}-\dfrac{1}{3}$ hectare

= $\dfrac{9-4}{12}$ hectare

= $\dfrac{5}{12}$ hectare

(2)

Given, Dina bought $\dfrac{2}{3}$ yard of yellow yarn and $\dfrac{4}{5}$ yard of blue yarn for her crocheting hobby.

Then the mathematical expression of the total length of yarn she buy bought

= $\dfrac{2}{3}+\dfrac{4}{5}$ yards

Thus the required total length

= $\dfrac{2}{3}+\dfrac{4}{5}$ yards

= $\dfrac{10+12}{15}$ yards

= $\dfrac{22}{15}$ yards
