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!
