How do you convert 100 millimeters to meters?

100 mm = 0.1 m

Let ##x## represent the unknown count of metres

Known: 1000 millimetres (mm) = 1 metre (m)

Using the method of ratios:

##(“metres”)/(“millimetres”) -> (“m”)/(“mm”) = 1/1000##

So we need to solve for:

##(“m”)/(“mm”) = 1/1000 -= x/100## …………………………………………………………………….. Note: In ratio, for multiply or divide, what you do to the bottom you do to the top. …………………………………………………………………….. We need to change 1000 into 100

##=>(“m”)/(“mm”) -= (1-:10)/(1000-:10) -= x/100##

##=>(“m”)/(“mm”)=0.1/100= x/100##
