Question

How many times larger ? Is 1.815x10^3 and 4.975x10^12??????

Answer 1

For this case we have the following data:

Debt in September 2015:$1.815 * 10^{13}$

Debt in September 2005:$4.975 * 10^{12}$

The debt in September 2015 can be rewritten as follows:

$18.15 * 10^{12}$

In this way, we divide the 2015 debt between the 2005 debt, obtaining:

$\frac{ 18.15 * 10^{12}}{ 4.975 * 10^{12} }=3.65$

Thus, the 2015 debt is 3.65 times larger than the 2005 debt.

Answer:

3.65 times larger

Answer 2

4975000000000-1815=4974999998185
