Answer:To determine how many 18.5 cm long strips Mark can make from a 4 meter (400 cm) strip of leather, follow these steps:1. **Convert the length of the leather strip to centimeters:** - 4 meters = 400 centimeters.2. **Divide the total length of the leather by the length of each strip:** - Number of strips = Total length / Length of each strip - Number of strips = 400 cm / 18.5 cm ≈ 21.62Since Mark cannot make a fraction of a strip, he can make **21 complete strips** from a 4 meter leather strip.
