Question

a cookie recipe calls for $2\frac{3}{4}$ cups of flour. carlos is baking a double batch.
hint: double = 2
how many cups of flour does he need?
enter the whole number

Explanation:

Step1: Convert mixed number to improper fraction

$2\frac{3}{4} = \frac{2\times4 + 3}{4} = \frac{11}{4}$

Step2: Multiply by 2 for double batch

$\frac{11}{4} \times 2 = \frac{22}{4} = \frac{11}{2}$

Step3: Convert back to mixed number

$\frac{11}{2} = 5\frac{1}{2}$

Answer:

$5\frac{1}{2}$
