In order to find the number times something is larger than something, you have to use division where you divide the larger number by the smaller number.

So:

$\frac{3.19*10^8}{8.23*10^5} =387.6063183$

I'm not sure how much you want to round to, but the answer is 387.6063183 times.

You can make sure by multiplying the smaller number by 387.6063183 and you should get the larger number:

$8.25*10^5*387.6063183=3.19*10^8$

Answer:

39/50

Step-by-step explanation:

Rewrite the decimal number as a fraction with 1 in the denominator

0.78=0.781

Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100

0.781×100100=78100

Find the Greatest Common Factor (GCF) of 78 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,

78÷2100÷2=3950

Therefore

X=3950

In conclusion,

0.78=3950
