1/2

2/4
4/2
Answer:
2
Step-by-step explanation:
To find the slope of a line given two points you could use the formula: .
However, what I'm fixing to do is equivalent to that except I think easier to remember.
You line up the points vertically and subtract, then put 2nd difference over 1st difference.
Like this:
( 3 , 4)
- ( 5 , 8)
---------------
-2 -4
So the slope is -4/-2=4/2=2.
The slope is 2.
In June, Riley finished 40% of the questions in her packet.
How many more questions had Riley finished than Annabel?
Riley finished 18 more questions than Annabel, as per the given condition.
Given that,
Annabel and Riley were given a homework packet of 120 math questions to finish over the summer. Annabel finished 25% of the questions in her packet. In June, Riley finished 40% of the questions in her packet.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Question finished by Annabel = 25% of 120 = 0.25 × 120 = 30
Question finished by Riley= 40% of 120 = 0.40× 120 = 48
Difference in the question = 48 - 30 = 18
Thus, Riley finished 18 more questions than Annabel, as per the given condition.

Answer:
24 piano lessons
Step-by-step explanation:
$0.18: One time
$4.32: ? times
You have to divide 4.32 by 0.18 which will give you 24. So Jennifer practiced 24 times. :)
I hope that helps! :D
P.S. I don't know how you're supposed to do it (i.e. proportions, ratios, etc.), so that's why I did it the way I learned. I just want to say: there are more ways to do this problem. :)
