Question

Which of the following is the solution to the equation 4/5n = 20? (3 points)


n = 4

n = 12

n = 16

n = 25

Answer 1

n=25

Answer 2

Step 1: Multiply 5 on both sides

Answer 3

\[\frac{ 4n }{ 5 }=20\]

Answer 4

\[\frac{ 4n }{ 5 }\times5=20\times5\]

Answer 5

\[\frac{ 4n }{ 1\cancel{5} }\times1\cancel{5}=100\]

Answer 6

\[4n=100\]

Answer 7

Step 2: Divide both sides by 4

Answer 8

\[\frac{ 4n }{ 4 }=\frac{ 100 }{ 4 }\]

Answer 9

\[n=\frac{ 100 }{ 4 }\]

Answer 10

\[n=?\]
