b)1/3of the reamining land is needed for star forest what part of whole is needed for star forest?

Answer 1

Answer:

one third is needed

1/3 ofcourse if this is needed

Answer 2

a) The remaining part of land for other needs is 3/5

b) The land need for star forest in whole land is 1/3 part

Given:

The land needed for butterfly park = 2/5 of total land

To find:

a)how many part of land is remaining for other needs?

b)1/3 of the remaining land is needed for star forest what part of whole is needed for star forest?

Solution:

Let 1 unit be the total measurement of land

From given data 2/5 of total land is needed for butterfly park

The land needed for butterfly = 2/5 of 1 unit  = $\frac{2}{5}$  

then remaining land = 1 - 2/5 = 3/5

The remaining part of land for other needs is 3/5

Given 1/3 of the remaining land is needed for star forest

⇒ the land need for star forest = (1/3) 3/5 = 1/5

The land need for star forest in (3/5) part of land is 1/5

The land need for 1 unit land = $\frac{(1/5)}{(3/5)} (1)$ = $(\frac{1}{5} )(\frac{5}{3} )$ = 1/3

a) The remaining part of land for other needs is 3/5

b) The land need for star forest in whole land is 1/3 part
