To find out how many times larger \( 6.255 \times 10^{10} \) is than \( 1.5 \times 10^{8} \), you can divide the first number by the second number:
\[ \frac{6.255 \times 10^{10}}{1.5 \times 10^{8}} \]
This can be simplified by dividing the coefficients and subtracting the exponents:
\[ \frac{6.255}{1.5} \times 10^{10-8} = \frac{6.255}{1.5} \times 10^{2} \]
Calculating \( \frac{6.255}{1.5} \):
\[ \frac{6.255}{1.5} = 4.17 \]
Now multiply by \( 10^{2} \):
\[ 4.17 \times 100 = 417 \]
So, \( 6.255 \times 10^{10} \) is 417 times larger than \( 1.5 \times 10^{8} \).
Thus, the answer is 417.
