<p>No, this is not a way that you can <em>accurately calculate</em> this ratio, because trading is often an off-blockchain event. The sequence of events looks something like this:</p>

<ol>
<li>You send bitcoins to the exchange, using the blockchain. (Or you send fiat money to the exchange.)</li>
<li>You make any number of trades internally to the site. The blockchain is not involved, only ledgers controlled by the site are updated.</li>
<li>You send bitcoins from the exchange to a wallet, using the blockchain. (Or withdraw fiat money.)</li>
</ol>

<p>Trading volume measurements are measuring step 2 there. That volume is not directly related to the blockchain volume. But, if you have other data too, to help you make sense of it, you could <em>estimate</em> the ratio in question.</p>

In addition, you can't even know what the actual amount being transaction on the blockchain is, due to change outputs, or transactions to yourself.

<p>How can I calculate the ratio between this two type of bitcoin transaction?
Is it correct divide the total volume USD of the data at this link:
<a href="http://data.bitcoinity.org/markets/volume/5y?c=e&amp;r=week&amp;t=a&amp;volume_unit=btc" rel="nofollow">http://data.bitcoinity.org/markets/volume/5y?c=e&amp;r=week&amp;t=a&amp;volume_unit=btc</a></p>

<p>by the total transaction volume (USD) of all the blockchain transaction?</p>

No, this is not a way that you can *accurately calculate* this ratio, because trading is often an off-blockchain event. The sequence of events looks something like this:

1. You send bitcoins to the exchange, using the blockchain. (Or you send fiat money to the exchange.)
2. You make any number of trades internally to the site. The blockchain is not involved, only ledgers controlled by the site are updated.
3. You send bitcoins from the exchange to a wallet, using the blockchain. (Or withdraw fiat money.)

Trading volume measurements are measuring step 2 there. That volume is not directly related to the blockchain volume. But, if you have other data too, to help you make sense of it, you could *estimate* the ratio in question.
