which is similar to n:1 where ![n=1.75](https://tex.z-dn.net/?f=n%3D1.75)
<u>Step-by-step explanation:</u>
Here we have to Express in the form n:1 give n as a decimal 21:12 . Let's find out:
Given ratio as 21:12 . Let's convert it into n:1 , where n is decimal
⇒ ![21:12](https://tex.z-dn.net/?f=21%3A12)
⇒ ![\frac{21}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B12%7D)
⇒ ![\frac{3(7)}{3(4)}](https://tex.z-dn.net/?f=%5Cfrac%7B3%287%29%7D%7B3%284%29%7D)
⇒ ![\frac{7}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B4%7D)
⇒
{ dividing denominator & numerator by 4 }
⇒ ![\frac{\frac{7}{4}}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B7%7D%7B4%7D%7D%7B1%7D)
⇒ ![\frac{1.75}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B1.75%7D%7B1%7D)
⇒
which is similar to n:1 where ![n=1.75](https://tex.z-dn.net/?f=n%3D1.75)
I'm not quite sure what you mean.
the factors can't be 1.
the factors have to be odd.
they have to be the same.
offhand i would say 3*3*3*3 would be equal to 9*9 = 81.
the number 81 has 4 odd factors that are all the same.
can't be 1 because 1 doesn't counts as a factor.
a prime number has 2 factors.
1 and itself.
every number has a factor of 1 and itself.
