Step-by-step explanation:
Stairs because they can’t possibly walk up the stairs cause then they’ll fall
For this case we have the following expressions:
70,000,000
7,000,000
If we divide the first expression by the second we have:
![\frac {70,000,000} {7,000,000} = 10](https://tex.z-dn.net/?f=%5Cfrac%20%7B70%2C000%2C000%7D%20%7B7%2C000%2C000%7D%20%3D%2010)
Thus, we have that the first expression is 10 times greater than the second expression.
Answer:
70,000,000 is 10 times greater than 7,000,000
