Question

a farmer uses four out of five equal strips of his land for wheat crops and 1/7 of his land for cereal crop. what frqction of his land is available for other crops. write also how u solve it

Answer 1

land for wheat crops=4/5
land for cereal crops=1/7
total land=1
land available=1-[4/5+1/7]
                       =1-33/35
                        =2/35

Answer 2

Answer:

$\frac{3}{35}$ of the land is available for other crops.

Solution:

From the given,

The part of land used for wheat crops is $\frac{4}{5}$

The part of land used for cereal crop is $\frac{1}{7}$

So, the land available for other crop is $1-\frac{4}{5}-\frac{1}{7}$

L.C.M of (4, 7) is 35

$\frac{1 \times 35-4 \times 7-1 \times 5}{35}$

$=\frac{35-28-5}{35}$

$=\frac{35-32}{35}$

$=\frac{3}{35}$

The remaining crops are grown in the $\frac{3}{35}$ unused part of the land
