Question

In \[64oz\] equals how many \[lb\]?

Answer 1

Hint:
Here we are given a weight quantity that is \[64oz\] and we are asked that it equals how many \[lb\] which an another weight quantity so while approaching such kind of the questions one should know about the \[oz\] that is ounce unit weight representation and the \[lb\]weight representation that is the pound system of the weight measurement is used in the Imperial and the United States that is legally defined as the \[0.453\] kilograms and the ounce unit of the weight measurement is the unit of the weight in the avoirdupois system which is equal to of the pound and equal to the grains. Now using this definition of the ounce we could convert it into the \[lb\] which we would see in the complete step by step solution.

Complete step by step solution:
In the above given question we are provided with the quantity of weight that is \[64oz\] we can see that it is in the ounce method of the weight quantity representation and we are asked to convert it into the that is equal to the pounds\[lb\] system of the weight measurement
So for converting the given weight that is as \[64oz\] into the desired \[lb\] we would use the a standard formula of the conversion of the pounds from the given ounces that is –
\[1oz = \dfrac{1}{{16}}lb\]
So using this and getting the equivalent for the given weight that is depicted as follows –
\[
  64oz = 64{\rm X}\dfrac{1}{{16}}lb \\
   = \dfrac{{64}}{{16}}lb \\
\]
Now by dividing we would get the desired answer that is –
\[\dfrac{{64}}{{16}}lb = 4lb\]
So the desired answer in the \[lb\] for the given \[64oz\] is-
 \[ = 4lb\]

Note:
While solving such kinds of the questions one should know about the different scales and the methods of the weight representation and their formulas of the conversion of the one weight system into the other as it is the primary step of the question. Also the care should be taken while doing the calculations as the whole precision and the correctness of the result depends upon that.
