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

Answer:

3.25 cm is the answer to $3\frac{1}{4}$ of a cm.

Step-by-step explanation:

Given:

$3\frac{1}{4}$ of a cm.

Solution:

Type I:

First we will see what is  $\frac{1}{4}$  

$3\frac{1}{4}=0.25$

i.e $\frac{1}{4}$  And  0.25 is SAME.

Now,

$3\frac{1}{4}= 3\ and\ 0.25=3+0.25=3.25\ cm$

Type II:

$3\frac{1}{4}=\frac{4\times 3 + 1}{4}\\3\frac{1}{4}\\=\frac{12+1}{4}\\=\frac{13}{4}\\=3.25\ cm$
