10 people can paint a building in 5 days. Each person paints \( \frac{\mathrm{1} }{\mathrm{10}} \) of the building in 5 days. In 5 days 7 people would paint \(7 \times \frac{\mathrm{1} }{\mathrm{10}} \) of the building In 5 days 7 people would paint \(\frac{\mathrm{7} }{\mathrm{10}} \) of the building.
