The amount of cloth needed to make 1 headband is 10 meters.
<h3>Unit value</h3>
- Number of headbands Anne made = 6
- Total clothes used = 3/5 meters
Cloth needed to make 1 headband = Number of headbands Anne made / Total clothes used
= 6 ÷ 3/5
= 6 × 5/3
= (6 × 5) / 3
= 30/3
= 10 meters
Therefore, the amount of cloth needed to make 1 headband is 10 meters.
