Question

gallons of lemonade ordered on tuesday
x = 1 order
how many customers ordered ½ gallon or more?
□ customers
what was the most common size ordered?
□/□ gallon

Explanation:

Step1: Convert ½ to eighths

$\frac{1}{2} = \frac{4}{8}$

Step2: Count orders ≥ 4/8

Orders at $\frac{4}{8}$: 1; $\frac{5}{8}$: 4; $\frac{7}{8}$:1; $1$:1. Sum: $1+4+1+1=7$

Step3: Find most frequent order

Count each size: $\frac{1}{8}$:1, $\frac{2}{8}$:1, $\frac{3}{8}$:3, $\frac{4}{8}$:1, $\frac{5}{8}$:4, $\frac{7}{8}$:1, $1$:1. Highest count is 4 at $\frac{5}{8}$.

Answer:

7 customers
$\frac{5}{8}$ gallon
