Answer 1

Answer:nupur walked more 1/35 km

Step-by-step explanation:

Rupali walked 2/5 km

Nupur walked 3/7 km

Rupali=(2×7)/(5×7)=14/35

Nupur=(3×5)/(7×5)=15/35

15/35 - 14/35 = 1/35

Answer 2

Answer:

Step-by-step explanation:

Concept:

The concept of frcation will help us to solve the question.

Given:

Rupali walked $\frac{2}{5} km$ and Nupur walked $\frac{3}{7} Km$ during the weekend.

To Find:

We have to know who walks more than whom and by how much .

Solution:

We have to make the denominator of both the fraction to know who walks more.

Rupali walked $\frac{2}{5} km=\frac{2 \times 7}{5 \times 7} =\frac{14}{35} Km$ .

Nupur walked $\frac{3}{7} Km=\frac{3 \times 5}{7 \times 5} =\frac{15}{35} km$.

Now the denominator of second fraction is greater than first.

So Nupur walks more than Rupali during the weekend.

Now we have to substract $\frac{14}{35} Km$ from $\frac{15}{35} Km$ .

$\frac{15}{35} -\frac{14}{35}$

After calculation we will get the value is $\frac{1}{35}$.

Therefore, Nupur walked $\frac{1}{35} Km$ more than Rupali.
