Answer: 4.86
Step-by-step explanation: Since n is being divide by 0.9, to get n by itself, we need to multiply by 0.9 on both sides of the equation.
On the right side of the equation, the 0.9's cancel and we have n. On the left side of the equation, we have 0.9 × 5.4 which is 4.86.
Therefore, 4.86 = n.
