Answer:
5/6 books
Step-by-step explanation:
We know that Mark read 2 1/2 books last week. This week, he read a bit more with 3 1/3 books.
To find how many more books he read, we must subtract 2 1/2 from 3 1/3:
3 1/3 - 2 1/2
Let's convert these into improper fractions first:
3 1/3 = (3 * 3 + 1) / 3 = 10/3
2 1/2 = (2 * 2 + 1) / 2 = 5/2
Now, we have:
10/3 - 5/2
In order to subtract these, we must find a common denominator. For 2 and 3, the LCM is 6, so we can use that as our common denominator:
10/3 * 2/2 = 20/6
5/2 * 3/3 = 15/6
Finally, we have:
20/6 - 15/6 = (20 - 15) / 6 = 5/6 books

Answer:
Step-by-step explanation:
When y varies jointly as x and z, the equation is written ...
y = k·x·z
Here, the joint variation is not with z, but with z². There is also an inverse variation with w, so the entire relation is ...
y = k·x·z²/w
We want to find the value of k for the given values of the variables. So, we can solve for k to get ...
Then the equation of variation is ...
