Question

Ariel solved the equation below.
7.9÷n=0.79
what value of n makes the equation true.​

Answer 1

n = 10

Explanation:

Solve for n:

7.9/n = 0.79

7.9/n = 79/(10 n) and 0.79 = 79/100:

79/(10 n) = 79/100

Take the reciprocal of both sides:

(10 n)/79 = 100/79

Multiply both sides by 79/10:

Answer: n = 10
