Since we have lbs given as $\dfrac{3}{4}lbs$ . And we have to convert them into ounces. So as from the hint, we can say that one lb is equal to $16{\text{ ounces}}$ .

So on comparing this with the question and using the unitary method, we can write it as

As one lb is equal to $16{\text{ ounces}}$ .

Therefore, for the $\dfrac{3}{4}lbs$ , it will be equal to

Since we can see that the numerator and denominator can be made simpler so solving it and we get

$ \Rightarrow 16 \times \dfrac{3}{4}$

And on solving the above multiplication, we will get the value as

$ \Rightarrow 12{\text{ }}ounces$

Therefore, $\dfrac{3}{4}lbs$ is equal to $12{\text{ }}ounces$ .

The full form for lbs will be Pound-mass or we can say it Pound. This word has come from the Roman word which is Libra and it is noted as ‘lb’ or ‘lbs’.
