Answer 1

here is ur answer...

b)1:1000

Answer 2

A line of 10 metres is shown by 1 cm on a scale. Its representative fraction (RF) is 1:1000. (Option b)

• Any large value can be represented on a scale by calculating its representative fraction.
• Since the actual line is 10 metres long, it can also be expressed as 1000 cm.
• Now, this will be expressed as a ratio by taking the represented value and the actual value.
• So, the RF becomes represented value: actual value=1 cm:1000 cm i.e., 1:1000.
