2,5 m to 75 cm as ratio in its simplest form​
zhannawk [14.2K]

Answer:

10 : 3

Step-by-step explanation:

Convert one of the measurements so that it is in the same form as the other.  (Easiest to convert m to cms so we are not working with decimals)

2.5 m = 2.5 x 100 = 250 cm (since there are 100 cm in a meter)

Therefore, as a ratio:

250 : 75

We can divide both by 5:

50 : 15

We can further divide by 5:

10 : 3

(no further simplifying)

So 2.5 m to 75cm as a ratio is 10 : 3
