Question

35 a baker uses $2\frac{1}{2}$ cups of flour for one batch of cookies and $1\frac{1}{4}$ cups for another. how much flour did the baker use in total? show your calculation

Explanation:

Step1: Convert mixed numbers to improper fractions

$2\frac{1}{2} = \frac{5}{2}$, $1\frac{3}{4} = \frac{7}{4}$

Step2: Find common denominator

$\frac{5}{2} = \frac{10}{4}$

Step3: Add the two fractions

$\frac{10}{4} + \frac{7}{4} = \frac{17}{4}$

Step4: Convert back to mixed number

$\frac{17}{4} = 4\frac{1}{4}$

Answer:

$4\frac{1}{4}$ cups of flour
