Question

An onion soup recipe calls for 3 2/3 cups of chopped onions Katrina has already chopped 1 1/3 cups of onions she wants to know how many more cups she needs to chop what X be the number of cups of onions Katrina still needs to chop write an equation to describe the situation

Answer 1

To determine the number of cups she still needs to chop we need to subtract the amount she already chopped to the amount she needs, then we have the equation:

$x=3\frac{2}{3}-1\frac{1}{3}$

This can be written as:

$x+1\frac{1}{3}=3\frac{2}{3}$

Now, we solve it:

$\begin{gathered} x=3\frac{2}{3}-1\frac{1}{3} \\ x=\frac{11}{3}-\frac{4}{3} \\ x=\frac{7}{3} \end{gathered}$

Therefore she needs to chop 7/3 more cups of onions.
