Answer:

10 times greater

Step-by-step explanation:

When you write these as numbers, you get:

800,000,000 (8 hundred million place)

80,000,000 (8 ten million place)

Then divide the greater number by the less number:

800,000,000/800,000,00

make this easier by eliminating 0's:

80<u>0,000,000</u>/8<u>0,000,000</u>

80/8

10

10 times greater is your answer

Hope this helps!
