Question

65% of the shop owners in town A already installed the closed circuit television system (CCTV). Find the ratio of the shops that have installed CCTV to the shops that have not installed CCTV in town A.

a) 13:7

b) 7:13

c) 3:2

d) 2:3

Answer 1

The ratio of shops with CCTV to those without in town A is 13:7, calculated by simplifying the percentages 65% for shops with CCTV and 35% for those without.

Step-by-step explanation:

The question is asking to find the ratio of shops with CCTV to those without CCTV in town A. We know that 65% have installed CCTV, implying that 35% have not installed it since the total must add up to 100%. To find the ratio, we can use the percentages directly. The ratio of shops with CCTV to those without would be 65:35, which can be simplified by dividing both numbers by their greatest common divisor, which is 5. This gives us a simplified ratio of 13:7. Therefore, the correct answer is option a) 13:7.
