Answer 1

20%

Explanation:

• 2 m = 200 cm

• We are required to find: what percentage of 2m is 40cm.

• Required percentage
  `=(40)/(200)* 100`

• Required percentage
  `=(4000)/(200)`

• Required percentage
  `=20%`

Answer 2

20%

Explanation:

the units of measure must be the same, so

2m = 2 × 100 cm = 200 cm

then

`(40)/(200)` × 100%

= 0.2 × 100%

= 20%
