Answer 1

Answer:

Step-by-step explanation:

225 papers have a thickness of 18 cm

thus 1 paper will have a thickness of 18/225 cm

now 7 more cm were added to the bundle

as 1 paper has a thickness of 18/225 cm to get 7 cm we have to multiply

225/18 * 7

thus 225/18*7 papers were added to the group
