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)
Answer:
Step-by-step explanation:
K=cd formula hope this helps
5(3x-6/7)
1) 5×3x=15x
ii)5×-6/7=-30/7
2)15x=-30/7 3)15x/15=-30/7/15 (4)x=-2/7or -
0.9
steps
1)multiply 5 with what you have in the bracket.
2)divide both sides by15 to get the value of x
3)and whatever you get is the answer.
