Question 4.
Which is greater :
i)

Solution:

Now,
we have to find greater of

To compare fractions, we make denominator equal.

ii)

Solution:

Now,
we have to find greater of $$\frac{3}{7}$$ & $$\frac{2}{7}$$
Since denominator is same, number with greater numerator is greater.i.e., $$\frac{3}{7}>\frac{2}{7}$$
∴ Thus $$\frac{1}{2}$$ of $$\frac{6}{7}$$ is greater

Question 5.
