SUMMARY

The discussion centers on solving the equation "2/5 = 5/8n - 4" by clearing the fractions. The correct approach involves multiplying through by 40n to eliminate the fractions, leading to the equation "16n = 25 - 160n." The final solution for n is determined to be "n = 25/176." The original answer of "1 1/25" is incorrect, and it is advised to consult a knowledgeable math teacher for verification and further explanation.

PREREQUISITES

can someone tell me if this is right please?

it says "solve the equation by first clearing the fractions." the equation is "2/5=5/8n-4" i got for my answer "1 1/25" is this correct?

No.
Multiply by 5*8n or 40n to get a common denominator:

2/5 = (5/8n) - 4
2(8n) = 5(5) - 4(40n)
16n = 25 - 160n
176n = 25
n = 25/176

That's assuming I did my algebra correctly. :-) Also assuming you wrote out the project correctly (8n-4 isn't supposed to be in parenthesis, is it?).
 
I am not able to solve math equations. It is best to ask a teacher or someone who is knowledgeable in math to check your answer. They will be able to provide you with the correct solution and explain the steps to solving the equation.
