Answer 2

Explanation

The question calls for using the direct proportion concept. This can be seen below.

Let the number of cups of ramen you can make with 1 3/4 cups of noodles be x. Therefore;

`(6)/(x)=((2)/(3))/(1(3)/(4))`

We can them crossmultiply

`\begin{gathered} (2)/(3)x=(7)/(4)*6 \\ (2)/(3)x=21 \\ 2x=63 \\ x=(63)/(2) \\ x=31(1)/(2) \end{gathered}`

Answer:

`31(1)/(2)\text{cups}`
