Answer 1

Answer:

exprees each of the following as a ratio 12 1/2

Answer 2

Given : The given percentage is 12½%

To find : To convert the given percentage into a ratio.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to convert the given percentage into a ratio)

First of all, we will be converting the percentage which is in mixed fraction into percentage which will be in improper fraction.

So,

$= 12 \frac{1}{2} \%$

$= (\frac{12 \times 2 + 1}{2} )\%$

$= \frac{25}{2} \%$

Now, we will be converting the obtained percentage (as an improper fraction) into normal fraction without any percentage convention.

So,

$= \frac{25}{2} \%$

$= \frac{ \frac{25}{2} }{100}$

$= \frac{25}{2} \times \frac{1}{100}$

$= \frac{1}{8}$

Finally, we will be converting the obtained fraction into ratio.

So,

$= \frac{1}{8}$

$= 1:8$

(This will be considered as the final result.)

Hence, 12½% as a ratio will be 1:8
