I am confused. Did you use the fill flash here? Almost looks like it. 

1) If you did not use a flash then using a flash would help. BUT ..
2) If you did use the flash, then setting the camera to A mode and selecting a smaller aperture would help. Depending on camera model, the flash will force the speed to be quite slow...typically 1/125 or 1/200. Now the camera's operating systems are reading the exposure on the girls and they are in the shade. Therefore a typical default setting in P mode would be f5.6 and maybe 1/125 second. Well the bright sky requires a fraction of the exposure and therefore is burned. You need less exposure on the sky. Sooooo ... if the camera was set at (say) f 11 and the default flash speed was 1/125 that may help. But you are limited. Using the "sunny 16" rule, the EV (exposure value) of that sky at ISO 200 would be close to the equivalent of f16 at about 1/200 or 1/250 second. But your flash won't may not work at those speeds so, you could reduce the ISO to 100. But it is also possible that with the on-board flash at 1/160 and f16 the girls will be underexposed, i.e. too dark. So selecting a slower ISO may help as well. It is never perfect.

This is a perfect situation for a flash and no mater how complicated the above ramblings may see, try fill flash in this situation again. Should work for you. Start with the camera set in P mode and go from there. 

The other option is to put the girls in the sun so they are reflecting the same levels of light as the sky. If the sky is not important then put the girls in open shade (as you have done) BUT this time select a background that is also in the shade. Bright open shade is often better on people than bright sun.

Cheers!

Thanks, my friend. I will try that technique and post the results.

Yes, Clive. I did use the flash, but my mode on the Alpha 350, was Aperture mode, with the aperture size large ( I think around 2.5). I will try what you suggest. Thanks again

Barry,

Aha! Yes at such a wide aperture the sky would burn. Try it again at (say) f8 or f11 or more.

Also consider a different set up so the girls and background are shaded or so they are all in the sun. 

Good luck!

So Clive, my friend............I should change to P mode, set aperture at f/11, speed at 1/125 and fill flash, and ISO 100. And of course hope for the best.

Barry. If you are going to change the aperture to correct this, then set the camera on A mode. If you set on P and adjust the aperture, then the next shot will revert to where the P mode wants it. Once set in A it stays at a fixed aperture.

You may find at the narrow aperture (say f11) that the flash may not have enough power to expose the girls. Depends. 

The situation you showed really is quite is difficult.

Cheers!

EDIT .. I knew I could find an example....this was a few years ago ... my dad was sitting in total shade. The background was in sun.

Hi
Fill flash will do an ok job but to get a better result you need a flash gun and use high speed flash or manual exposure for background and a manual flash setting to light the subjects.

It's still fill flash whether you use the built in flash or add a flash gun :)
But yes, an added flash gun is more powerful and will do even more to improve the scenario...

You need to either increase your shutter speed to tame the background or increase your aperture if you can not get it under control with shutter speed.
P mode is for ..... well not professional, put it that way.
Manual mode is what you need, this is not a difficult shot if you are in manual mode and understand exposure.
Your flash will expose the subjects, don't worry about that.
Adjust your shutter speed for the background, then pop up that flash, then you got it.
