Answer 1

Explanation

you can easily solve this by using a rule of three.

Step 1

the least one of these balls can weigh 383 grams,convet grams into ounces

Let

x represents the number of ounces in 383 grams

then

if

$\begin{gathered} 28.35\text{ grms}\Rightarrow1\text{ ounces} \\ 383\text{ grams}\Rightarrow\text{x ounces} \end{gathered}$

the ratio is the same, then

$\begin{gathered} \frac{28.35}{1}=\frac{383}{x} \\ 28.35x=383\cdot1 \\ x=\frac{383}{28.35} \\ x=13.5 \end{gathered}$
