Question

How many cups are there in nine ounces?

Answer 1

Hint:
First we will find the relation between ounces and cups and that is \[8\] ounces \[=1cup\] and now for unit conversions we will calculate the cups in unit ounce and then for the required value in ounces we just multiply it with the multiplication factor and that is the number of cups in unit ounce.

Complete step by step solution:
As we already know that \[8\text{ ounces }=\text{ 1 cup}\]
Then, we can calculate the number of cups in \[\text{1 ounce}\]
\[\Rightarrow 1\text{ ounce=}\dfrac{1}{8}cups\]
Now in \[9\] ounces the number of cups are
\[\begin{align}
  & \Rightarrow 9\times \dfrac{1}{8} \\
 & \Rightarrow 1.125\text{ }cups \\
\end{align}\]

Hence, \[1.125\text{ cups}\] are there in \[9\] ounces

Note:
In these types of questions we just apply the unitary method that first calculates the for the unit value then for the given value by multiplying with the multiplication factor. The common avoirdupois ounce (approximately 28.3 g).
