Question

25 mm is equal to how many cm?

Answer 1

25mm = 2.5cm

Explanation:

Using the `color(blue)"related conversion"`

That is `color(red)(bar(ul(|color(white)(a/a)color(black)(1cm=10mm)color(white)(a/a)|)))`

`rArr25mm=(2xx10mm)+(1/2xx10mm)`

so we have `2+1/2"cm"=2 1/2=2.5"cm"`

or using `color(blue)"ratio method"`

`(1cm)/(10mm)=(xcm)/(25mm)" require to calculate value of x"`

using `color(blue)"cross-multiplication"`

`rArr10x=25rArrx=(25cancel(mm))/(10cancel(mm))=2.5" cm"`
