Question

Sam bakes delicious cakes. A specific cake recipe requires $1$ lb of flour. If he had $8$ oz of flour with him, then the additional amount(in pounds) of flour to be added according to the recipe is

Answer 1

The cake recquires $1$ lb of flour and Sam has $8$ oz of flour with him.

We know $1$ lb $=16$ oz
$\therefore$ Amount of flour required $=16-8=8$ oz
Now, Let $8$ oz be $x$ lb
$\Rightarrow \frac{1\text{lb}}{16\text{oz}}=\frac{x\text{lb}}{8\text{oz}}$

$\Rightarrow x\text{lb}=\frac{8}{16}\text{lb}=0.5\text{lb}$
$\therefore 0.5$ lb flour will be required for the recipe.
