Question

nadia has logs that are $\frac{1}{2}$ m long.
how many logs does she need?
12 logs
which multiplication equation
represents the situation?
$12 \times 6 = \frac{1}{2}$ $12 \times \frac{1}{2} = 6$
$6 \times \frac{1}{2} = 12$
(image shows a 6 m length, a log segment of $\frac{1}{2}$ m, and 12 logs placed to cover 6 m)

Explanation:

Step1: Define total length needed

Total length = $6$ m

Step2: Define single log length

Single log length = $\frac{1}{2}$ m

Step3: Calculate number of logs

Number of logs = $\frac{\text{Total length}}{\text{Single log length}} = \frac{6}{\frac{1}{2}} = 6 \times 2 = 12$

Step4: Match multiplication equation

The equation representing "number of logs × length per log = total length" is $12 \times \frac{1}{2} = 6$

Answer:

1. Number of logs: 12
2. Correct multiplication equation: $12 \times \frac{1}{2} = 6$
