Mohammad's height is 169cm and Fatima's 'ht. is 156cm.The frame sizes of their bikes are in the same ratio as their hts.The frame size of...

Let Mohammed's height be Mb =
169

And let Fatima's height be Fh =
156

Also, given Mohammeds bike (Mb) =
52

Then have the same ration for their
bikes:

==> we will rewrite:

Mh =
169   ==>   Mb = 52

Fh = 156  ==>    Fb =
?

Now since they have the same ratio, then we will cross
multiply:

==> 169*Fb = 52*
156

==> Fb = 52*156/
169

==> Fb =
48

Then Fatima's bike height is
48
