Answer:
Step-by-step explanation:
first, we need to do
28/8
=3.5
now we need to do
5 x 3.5
=17.5
x=17.5
x = 17.5
5/8 = x/28
=> 5(28) = 8x
=> 140 = 8x
=> 8x = 140
=> x = 140/8
=> x = 70/4
=> x = 35/2
=> x = 17.5

To get the answer just use the numbers from the table which you have stated and you are right, you do get a long decimal.
5.69*10^26 / 6.42 * 10^23 = 886.29
which rounds to 886
