10 M : ?
10dcm : 1 m​

Answer 1

The equivalent of 10 m is 100 dcm

Step-by-step explanation:

This question is Mathematics not Health; however, the solution is as follows

Given

10 dcm = 1 m

Required

Find the equivalent of 10 m

Note that: dcm represents decimetre and m represents metres

Let x represents the equivalent of 10 metres in decimetres

Provided that

`1 m = 10 dcm`

`10 m = x`

Using cross multiplication:

`x\ dcm * 1\ m = 10\ dcm * 10\ m`

Divide both sides by 1 m

`(x\ *\ 1\ m)/(1\ m) = (10\ dcm * 10\ m)/(1\ m)`

`x = (10\ dcm * 10\ m)/(1\ m)`

`x\ = 10dcm * 10`

`x\ = 100\ dcm`

Hence, the equivalent of 10 m is 100 dcm
