Answer:
Step-by-step explanation:
A rectangular prism is a three-dimensional solid.
A rectangular prism has six faces (each one of these faces are rectangles), eight vertices and twelve edges.
You know that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters ().
Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:
Where is the volume of one layer.
Substituting, you get:
<h2>Answer</h2>
Janice convert a mixed number to the wrong improper fraction
<h2>Explanation</h2>
To convert a mixed number to an improper fraction, we multiply the whole number by the denominator of the fraction and add the result to the numerator of the fraction; while keeping the denominator of the fraction as the denominator of the improper fraction.
Let's convert our mixed numbers to improper fractions:
To convert we multiply the whole number 10 by the denominator of the fraction 6, and then we add the result to the numerator 5:
Now let's convert :
Notice that Janice converted as , which is incorrect.
Since , we can conclude that Janice convert a mixed number to the wrong improper fraction.
Examples of How to Find Unit Rate or Unit Price
Ryan purchased 3 apples for $1.80. What is the unit price, or the cost of one apple?
<span>We want to know the price per apple unit so we set up a ratio with the number of apples in the denominator. The total price goes in the numerator. So the fraction is 1.80/3.Complete the division: 1.80 ÷ 3 = .60. You can conclude that the per apple price unit rate is $0.60/1. Ryan paid a unit price of $0.60 per apple (60 cents per 1 apple = .60/1).</span>
The pottery store can make 176 coffee mugs in an 8 hour day. How many mugs can they make in one hour?
<span>We want to know the number of mugs made per hour unit so we set up a ratio with hours in the denominator. The total number of mugs made per day goes in the numerator. So the fraction is 176/8.Complete the division: 176 ÷ 8 = 22. You can conclude that the per hour mug-making unit rate is 22/1. The pottery store makes 22 mugs per hour (22 mugs per 1 hour = 22/1).</span>
Kylie can run 12 laps in 30 minutes. How many laps does she run per minute?
<span>We want to know the laps per minute unit so we set up a ratio with minutes in the denominator. The total laps goes in the numerator. So the fraction is 12/30.<span>Complete the division: 12 ÷ 30 = 0.4. You can conclude that the per minute lap unit rate is 0.4/1. Kylie can run 0.4 laps per minute (0.4 laps per 1 minute = 0.4/1).</span></span>
