Answer:
79/90 0r 29/33
Step-by-step explanation:
Let 10x=8.7 and 100x=87.7
We now have two equations. Subtracting the largest from the smallest:
100x=87.7
10x=8.7
-------------
90x=79
x=7990
Hence, 0.877777...=79/90.
Hopefully this helps!

Answer:
Step-by-step explanation:
Let be "x" the amount of miles light will travel in 4,200,000 seconds.
Rewrite 4,200,000 seconds in Scientific notation. Move the decimal point 6 places to the left. Then:
According to the exercise, light travels miles in 1 second.
Therefore, based on this data, you can set up the following proportion:
And finally, you must solve for "x" in order to find its value.
(Remember the Product of powers property: )
Then:
