Question

Simplify the ratio!
b) 50 cm : 1.25 m

Answer 1

`{40 \: cm}^(2)`

Explanation:

⇒ "1.25" was replaced by "(125/100)".

⇒

`(5)/(4)`

⇒

`(50 \: c \: . \: (5)/(4)) \: . \: m`

⇒ Divide "m" by

`(5)/(4)`

⇒

`(50 \: c \: . \: (4m)/(5) \: . \: m`

⇒

`{m}^(1) \: multiplied \: by \: {m}^(1) = {m}^(1 + 1) = {m}^(2)`

⇒ Final Result :

`{40 \: cm}^(2)`
