The product of two negatives and one positive will give you a negative number. Take the three numbers; -1, -1, and 1. There are two negatives and one positive.
-1 x -1 x 1 = 1 x 1 = 1 = positive number
So the possible answers are the positive numbers:
20 and 10

Based on the ratios given, the number of people in each service is 8000 in the army, 16000 in the navy and 24000 in the air force.
<h3>What is the number of people in each service?</h3>
Given that 48000 people are in the defence services.
The defence services comprises of the army, navy and air force.
- The defence services are in the ratio 1:2:3
To determine the number of people in each service:
Total ratio = 1 + 2 + 3 = 6
- Number of people in each service = each service ratio/total ratio × 48000
Number in army = 1/6 × 48000 = 8000 persons
Number in Navy = 2/6 × 48000 = 16000 persons
Number in air force = 3/6 × 48000 = 24000 persons
Therefore, the number of people in each service is 8000 in the army, 16000 in the navy and 24000 on the air force.

The graph below shows two lines that are parallel. As we can see, these lines have equal steepness, meaning they have equal slope
Circumference = π x d
= π x 12
= 37.699
Rounded off is 37.70
