Given:
Two numbers are 12 and 21
To find:
The factors of 12 and 21, then find the common factor and the greatest common factor.
Solution:
Two numbers are 12 and 21. The prime factors of these two numbers are
![12=2\times 2\times 3](https://tex.z-dn.net/?f=12%3D2%5Ctimes%202%5Ctimes%203)
![21=3\times 7](https://tex.z-dn.net/?f=21%3D3%5Ctimes%207)
From the above factorization, it is clear that the factor 3 is common in both. So,
Common factor (CF) = 3
Only 3 is common in factorization of both. So,
Greatest common factor (GCF) = 3
Therefore, the common factor is 3 and the greatest common factor is also 3.
Answer:
233.35488 km (Rounded to 233 km)
Step-by-step explanation:
If you convert miles to kilometers then you would use this conversion factor:
1 mile = 1.609344 km (or 1.61 km)
so in this case,
145 mile = 1.609344 km x 145
145 mile = 233.35488 km
I could also round it to 233 km.
Since your on a trip... i hope u enjoy ur journey to Las Vegas!
1/2 would not be a useful benchmark to compare these 2 fractions because both of them are greater than half. The benchmark fraction 1/2 is most useful when one fraction is less than half and the other more than 1/2. 5/8 is more than 4/8(1/2), and 9/10 is more than 5/10(1/2).
