Answer 2

• $\dfrac{1}{8}$ of a day is 3 hours

• $\dfrac{1}{48}$ of a day is 30 minutes

• $\dfrac{1}{2}$ of a Rupee is 50 paisa

• $\dfrac{2}{7}$ od one week is 2 days

• $\dfrac{1}{2}$ of one metre is 50 cm

• $\dfrac{2}{3}$ of a 1 minute is 40 seconds

Step-by-step explanation:

(1)

We know that, 1 day = 24 hours

So, the required fraction is

$\dfrac{3}{24}=\dfrac{1}{8}$

(2)

We know that, 1 day = 24 hours = 24 × 60 minutes = 1440 minutes

So, the required fraction is

$\dfrac{30}{1440}=\dfrac{1}{48}$

(3)

We know that, 1 Rupee = 100 paisa

So, the required fraction is

$\dfrac{50}{100}=\dfrac{1}{2}$

(4)

We know that, 1 week = 7 days

So, the required fraction is

$\dfrac{2}{7}$

(5)

We know that, 1 metre = 100 cm

So, the required fraction is

$\dfrac{50}{100}=\dfrac{1}{2}$

(6)

We know that, 1 minute = 60 seconds

So, the required fraction is

$\dfrac{40}{60}=\dfrac{2}{3}$

NOTE:

Do not forget to take both the numerator and the denominator with the same unit of measurement.
