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:

3.25 cm is the answer to [tex]3\frac{1}{4}[/tex] of a cm.

Step-by-step explanation:

Given:

[tex]3\frac{1}{4}[/tex] of a cm.

Solution:

Type I:

First we will see what is  [tex]\frac{1}{4}[/tex]  

[tex]3\frac{1}{4}=0.25[/tex]

i.e [tex]\frac{1}{4}[/tex]  And  0.25 is SAME.

Now,

[tex]3\frac{1}{4}= 3\ and\ 0.25=3+0.25=3.25\ cm[/tex]

Type II:

[tex]3\frac{1}{4}=\frac{4\times 3 + 1}{4}\\3\frac{1}{4}\\=\frac{12+1}{4}\\=\frac{13}{4}\\=3.25\ cm[/tex]
