6
The electrician can wire 6 rooms with 3 3/5 rolls of wire;
3 3/5= 18/5
18/5 divided by 3/5= 6
+ 1 = 3
First, multiply both sides by 3. / Your problem should look like: x + 3 = 9.
Second, subtract 3 from both sides. / Your problem should look like: x = 9 - 3.
Third, simplify 9 - 3 to 6. / Your problem should look like:
x = 6, which is your answer.

In this question, there are 3 conditions that need to be met
1. The number is 3-digit
2. Hundreds digit >7 (number that will fulfill it would be 8 or 9)
