Answer:
384 lamps
Step-by-step explanation:
This is simply a multiplication problem. From the question, we know that each fixture needs 4 lamps with a single room needing 16 fixtures.
The number of lamps required by each room is thus 16 * 4 = 64 lamps
Now, the total number of lamps required by 6 rooms is thus 64 * 6 = 384 lamps
The answer is 13
25/100 X 80/1
25/10 X 8/1
25 X 8 = 200
200 divided by 10 is 20
20/100 X 65/1
20 X 65= 1,300
1,300 divided by 100 is 13
