Question

timmy uses $1\frac{1}{2}$ cups of sugar for every 2 gallons of lemonade he makes. how many cups of sugar would timmy use if he makes 13 gallons of lemonade?
\square cups of sugar

Explanation:

Step1: Convert mixed number to improper fraction

$1\frac{1}{2} = \frac{3}{2}$ cups per 2 gallons.

Step2: Find sugar per gallon

$\frac{3}{2} \div 2 = \frac{3}{4}$ cups/gallon.

Step3: Calculate sugar for 13 gallons

$\frac{3}{4} \times 13 = \frac{39}{4} = 9.75$

Answer:

9.75
