Answer:
b. 4 (7 + 6)
Step-by-step explanation:
Finding the GCF between 28 and 24:
We keep dividing while both numbers can be divided by the same factor. So
28 - 24|2
14 - 12|2
7 - 6
There is no number for which 7 and 6 are both divisible by, so the GCF between 28 and 24 is 4.
Simplifying in function of the GCF:
Now, we put 4 in evidence, and divide the rest of the expression by 4. So

The answer is given by option b.
Answer:
0.40390 km
Step-by-step explanation:
1 cm = 1 / 100000 km
40390 cm
= 40390 / 100000
= 0.40390 km
