Answer:
2/45
Step-by-step explanation:
0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as: 
. Multiplying the two fractions results in 4/90 which can be simplified to 2/45.

Hey. Let me help you on this one.
In order for us to solve this problem, we will need to determine how much money Luke has earned from the sales this month, and find the total amount of sales in dollars.
I will also be attaching an image to this answer in case you still don't understand the question, or need extra help with your studies.
We know that Luke's salary is $3500, and anything above that amount of money comes from sales he makes. We also know that he only gets 15% from sales. Let's determine how much he earned from sales this month.
Luke has earned $1260 from the sales he made. Since it's only 15% of the full amount, we need to convert this value to 100%. We can do this by finding 1% of the unknown number, and multiplying it by 100 to show the full amount of sales.
Let's find 1% of the total amount of sales. Since 1260 is 15% of the unknown total, let's divide it by 15.
Great. $84 is 1% of the total amount of sales. All we need to do is multiply it by 100 to show 100% of the total amount of sales.
Awesome. We now know the amount of sales in dollars that Luke has brought to the company.
Answer: Total amount of Luke's sales in dollars is $8400
Answer:
Hey! The answer is <em>-4 5/12</em>
Step-by-step explanation:
<em>First, make all the mixed number into a improper fraction.</em>
<em>Next, find the least common multiple.</em>
<em>Than, adjust the fractions basied on the LCM.</em>
<em>Lastly, convert the improper fractions to mixed numbers</em>
<em>follow these steps in order to get -4 5/12 as your answer.</em>
<em>so therefore your answer will be:</em>
<em>-4 5/12</em>

<span>The original cost of the camera is $120.
Explanation:
6%=6/100=0.06. This means to find 6% tax on a sale, we multiply the amount of the sale by 0.06; this gives us 0.06x, since we don't know the cost of the camera.
We know the amount of tax is $7.20, so we have the equation 0.06x=7.20.
Divide both sides by 0.06:
0.06x/0.06 = 7.20/0.06
x=120.</span>
