Answer:

She would need [tex]4\frac{3}{8}[/tex] flour to make  [tex]2\frac{1}{2}[/tex] times the recipe.

Step-by-step explanation:

To make 1 recipe Amelia uses = [tex]1 \frac{3}{4}\ cups[/tex] of flour.

So, to make [tex]2\frac{1}{2}[/tex] times the recipe she would need =[tex]1 \frac{3}{4}\times 2\frac{1}{2}[/tex].

We evaluate the above mixed numbers by converting them to fraction(by multiplying denominator with whole number and adding to numerator and write as fraction of same denominator.).

[tex]=\frac{7}{4}\times \frac{5}{2}[/tex]

[tex]=\frac{35}{8}[/tex]

Then converting back to mixed number (by dividing the numerator by denominator and writing the quotient as the whole number and the remainder as fraction with same denominator.

[tex]\frac{35}{8}=4\frac{3}{8}[/tex]

So, she would need [tex]4\frac{3}{8}[/tex] flour to make  [tex]2\frac{1}{2}[/tex] times the recipe.
