Question

So I'm doing perimeter in my unit right now for home work but I'm struggling a bit for this one question. How many centimetres would 3 1/4 of a cm I'm not really sure!

Answer 1

3.25 cm is the answer to
`3(1)/(4)` of a cm.

Explanation:

Given:

`3(1)/(4)` of a cm.

Solution:

Type I:

First we will see what is
`(1)/(4)`

`3(1)/(4)=0.25`

i.e
`(1)/(4)` And 0.25 is SAME.

Now,

`3(1)/(4)= 3\ and\ 0.25=3+0.25=3.25\ cm`

Type II:

`3(1)/(4)=(4* 3 + 1)/(4)\\3(1)/(4)\\=(12+1)/(4)\\=(13)/(4)\\=3.25\ cm`
