I can see that one of the transactions has been confirmed, so your problem is half solved. For the other transaction you just need to wait. If you're experienced enough you might as well want to rebroadcast the stuck transaction with a higher fee.
The transaction fee you have included in both transactions is way too low. At the current state of the bitcoin network, there is not enough room in blocks to fit all of the transactions, so the miners pick only the transactions with higher fees.
Prevent from happening again
If you require your transactions to be confirmed in a short period of time, then you need to include a much higher miner fee. You can use the following site as a guide as to what the fee should be: https://bitcoinfees.21.co/
