First, we’re going to use this formula:
2nd number - 1st number
————————————— x 100%
1st number
If we plug in the numbers to this equation:
23-20
———- x 100%
20
And subtract 23 to 20, the answer to this equation is:
3
—- x 100% = 15%
20
In this case, the percent of increase is 15%.
Answer:
equation 1 has no solution
Step-by-step explanation:
when you compare each of the equations, all the equations gives a correct answer with the exception of equation 1
The answer is 7/20. 1/4= 5/20 and 3/5 = 12/20
What I did was find the GCF (greatest common factor) of both 4 and 5 which was 20. Then I multiplied both numerators by the same number I multiplied the denominator with. Afterwards I subtracted both numerators (12-5) and this equals to 7
Hope that helps
