Let's say you had the ratio 14:21
The GCF of the two values (14 and 21) is 7
14 = 7*2
21 = 7*3
We can divide both parts of the ratio by the GCF 7 to get
14/7 = 2
21/7 = 3
Meaning the original ratio 14:21 fully reduces to 2:3
So in short, we use the GCF to help fully reduce any ratio.
This also applies to fractions as well. We could have something like 9/33 fully reduce to 3/11 after dividing both parts (9 and 33) by the GCF 3.
The answer is d) mutually exclusive
Complete question :
On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?
Answer:
1.6 hours
Step-by-step explanation:
Given the function :
Time t taken for flying distance d is given by:
t = 1/500 * d
Tine taken to fly 800 miles;
d = 800 miles
t = 1/500 * (800)
t = 800 / 500
t = 1.6
Hence, time t = 1.6 hours
