Question

Amelie is making a recipe that uses 1 3/4 cups flour. She is making 2 1/2 times the original recipe.

Answer 1

Answer:

She would need $4\frac{3}{8}$ flour to make  $2\frac{1}{2}$ times the recipe.

Step-by-step explanation:

To make 1 recipe Amelia uses = $1 \frac{3}{4}\ cups$ of flour.

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

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.).

$=\frac{7}{4}\times \frac{5}{2}$

$=\frac{35}{8}$

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.

$\frac{35}{8}=4\frac{3}{8}$

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