So
[tex]2 \ \frac{1}{4} = \frac{9}{4} [/tex]
So,
total sugar he has to use in making full recipe is
[tex]2 \ \frac{1}{4} [/tex]
But he is only making
[tex] \frac{2}{3} [/tex]
of recipe
So we have to 'minus' this.
So as u see in the above picture"sry for bad handwriting'' when we subtract we get an improper fraction and then we convert it to mixed fraction...
So the answer is
[tex]1 \ \frac{7}{12 \:} of \: sugar[/tex]
hope it helps:-)
