Answer:
The answer is 7
Step-by-step explanation:
2 numbers are called relatively prime if their Greatest Common Factor is 1.
For example, GCF(2, 6) = 2, not 1, so 2 and 6 are not relatively prime.
whereas, GCF(3, 8)=1, so 3 and 8 are relatively prime.
3 sets of relatively prime numbers are :
{4, 5}, {7, 9}, {9, 16}
Answer:
{4, 5}, {7, 9}, {9, 16}
First problem: 24/3=8
24 km irl is 8 cm on the map
problem #2: 9 times 17 = 153
The cities are 153 miles apart
Answer:
Nonstop ride is 12 hours long.
Explanation:
With stopping time taken by train = 18 hours.
Without stopping time is reduced by 1/3.
Time for non stop ride = Time for stopping ride - (Time for stopping ride/3)
= 2 x Time for stopping ride/3
= 2 x 18 /3 = 12 hours.
So, nonstop ride is 12 hours long.
