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(2)/(3)-1(1)/(3)`

This can be written as:

`x+1(1)/(3)=3(2)/(3)`

Now, we solve it:

`\begin{gathered} x=3(2)/(3)-1(1)/(3) \\ x=(11)/(3)-(4)/(3) \\ x=(7)/(3) \end{gathered}`

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