Answer: 3 mirrors of painting
Explanation:
Based on the information given that Moore is making a mirror painting and that she used 2/4 of a meter of mirror for 1 painting.
Since she will make 6 paintings for sale, the meters of mirror that she will use will be:
= 2/4 × 6
= 1/2 × 6
= 3
Therefore, she'll use 3 meters of mirror.
