1/12c = 0.6
To remove a fraction you simply multiply it by its inverse fraction (take the original fraction and flip it! So, multiply it by 12/1 (which is the same as saying 12).
12(1/12c) = 0.6*12
The 12 cancels out leaving this:
c = 0.6 * 12
c = 7.2
If you don't have or are allowed to use a calculator. To compute that you simply make 0.6 into a fraction then multiply the numerator by 12. .6 is in the tenths place so you can write it like this:
6/10 simplifying it becomes, 3/5
3/5 * 12 = 36/5
Now! That was assuming 1/12c was written like this:
(1/12)c = 0.6
If it was actually written like this:
1/(12c) = 0.6 then you'll do this.
Multiply 0.6 by 12c. Which will get you 7.2c. After that you need to get c alone, so you divide both sides by 7.2. Yielding the result:
1/7.2 = c
c = 0.1389...
Answer:
$24
Step-by-step explanation:
For a markup, use the formula <em>a = ( 1 + p ) × w. </em>
!!! Remember, <em>a </em>is the selling price, and <em>w </em>is the original price !!!
!!! The <em>p </em>is the percent in decimal form. 20% as a decimal is 0.20 (move the decimal twice to the left) !!!
<em />
Inserting the values, it should look like <em>a = ( 1 + 0.20 ) × 20 </em>
<em>a = 1.20 × 20 </em>
<em>a = 24</em>
<em />
Hence, the new selling price is $24.
Hope this helps! :)
Answer: 17.5%
To convert from decimal to percent, just multiply the decimal value by 100. In this example we have: 0.175 × 100 = 17.5% (answer).
➥ The ease way:
1) Move the decimal point two places to the right: 0.175 → 1.75 → 17.5.
2) Add a % sign: 17.5%
Answer: 17.5%
To factor, we always have to look for common factors in the numbers given to us. In this case, in 1/2 and 6, the common factor is 1/2. Therefore, we will have to factor like so:
1/2d + 6 = 1/2 (d + 3)
Hope this helps!
