Answer:
3 1/3
Step-by-step explanation:
<u>Step 1</u> is to look at the problem.
Here, you notice that the first two numbers have fractions that are quarters. The total of those two fractions is 1/4 + 3/4 = 4/4 = 1.
So, the sum of the first two numbers is ...
1 1/4 + 3/4 = 1 +(1/4 +3/4) = 1 +1 = 2
<u>Step 2</u> is to add the next mixed number, which has a fraction with a different denominator. Since you have no fractions to add at this point, the sum is just ...
2 + 1 1/3 = 3 1/3

<em>Comment on adding fractions</em>
Generally, adding fractions requires you determine a common denominator. Often, you are asked to find the <em>least</em> common denominator, but that isn't necessary. Sometimes that can save the work of reducing the fraction that results, but sometimes it makes more work.
Here, a common denominator for fourths and thirds would be twelfths:
1/4 = 3/12
1/3 = 4/12
However, since adding the fourths results in an integer, no common denominator is necessary.
Answer:
The total cost is $16.96
The cost per photo is $1.06
Step-by-step explanation:
Hello!
<h3><u>
Part 1:</u></h3>
1 roll of film costs $4.79. 1 roll of film has 16 photos. To develop the 16 photos, you need to pay $12.17.
First, let's find the total cost for the film and the development for 1 roll of film:
- Total Cost = Cost of Film + Cost of developing
- Total Cost = $4.79 + $12.17
- Total Cost = $16.96
<u>The total cost of 16 photos is $16.96</u>
<u />
<h3><u>Part 2:</u></h3>
Now, we have to find the price per picture on the roll of film. We know that there are 16 shots on the film, so we can simply divide the total price by 16 to find the price per picture.
Divide:
- $16.96 ÷ 16
- ($16 ÷ 16) + ($0.96 ÷ 16)
- $1 + $0.06
- $1.06
<u>The price per photo is $1.06</u>
Answer:
8.75 miles.
Step-by-step explanation:
1.9 miles + 6.85 miles = 8.75 miles.
7x^4 - 21x^2a^2 + x^2a^2 - 3a^4
7x^4 - 20x^2a^2 -3a^4
