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.

Saili plants 4 saplings in a row, in her garden. The distance between two adjacent saplings is \(\frac{3}{4}\)m. Find the distance between the first and the last sapling.

Solution:

Saili plants 4 saplings, in a row.

The distance between each sapling = \(\frac{3}{4}\) m

Question 6.

Lipika reads a book for \(1 \frac{3}{4}\) everyday. She reads the entire book in 6 days. How many hours in all were required by her to read the book ?

Solution:

Number of hours read everyday = \(1 \frac{3}{4}\) hours

Number of days to read whole book = 6 days

Therefore,

Question 7.

A car runs 16 km using 1 litre of petrol. How much distance will it cover using \(2 \frac{3}{4}\) litres of petrol.

Solution:

Distance of car runs in 1 litre = 16km

∴ Car will run 44 km in \(2 \frac{3}{4}\) litre of petrol.
