I am working percentages increases and decreases with problems like From 24 pencils to 30 pencils (increase question) or From 20 miles to 11 miles ( decrease question) How can I check my answers of percentages to make sure they work? Please help!
Answers
30 pencils = ___%
30 - 24 = 6, so:
24 / 6 = 4 (it means that there are 4 sixes in 100%)
100% / 4 = 25%
Check: 25% * 24 = 25/100 * 24 = 1/4 * 24 = 6
30 - 6 = 24 (correct)
Answer: There was an increase by 25%
20 miles = 100%
11 miles = ___%
1 mile = 100% / 20 = 5%, so:
5 * 11 = 55 [percent]
100% - 55% = 45%
Check: 45% * 20 = 45/100 * 20 = 45/10 * 2 = 9/2 * 2 = 9
20 - 9 = 11 (correct)
Abswer: There was a decrease by 45%

The required fraction is given as 11/4, which is greater than one.
Given that,
A recipe calls for 2 3/4 cups of milk, how many cups of milk, written as a fraction greater than one, are used in the recipe is to be determined.
What is the fraction?
Fraction is defined as the number of compositions that constitutes the Whole.
What is simplification?
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
cup of milk in a recipe = 2 3/4
= 2 + 3 / 4 = 11/4 = 2.75 > 1
Thus, the required fraction is given as 11/4, which is greater than one.

Answer:
A. The rate of change of f is twice the rate of change of g.
Step-by-step explanation:
The first function is
The slope of this function is the coefficient of x. It is the same as the rate of change of f(x)
From the graph, g(x) passes through(-2,-4) and (0,2)
We use the slope formula: to find the slope of g(x).
Since 6=2(3), we conclude that, the rate of change of f is twice the rate of change of g.
