Start both at the same time, flip each when time runs out. The 5 minute will be turned 3 times totalling 15 minutes. The 8 minute will be flipped twice totalling 16 minutes. Once the 15 minutes is up on the 5 minute timers, there is one minute left on the 8 minute timer.

If i had a three minute eggtimer and a five minute eggtimer and i need to boil an egg for seven minutes how would you do this?
I would use my watch, or the timer function of my microwave. Or you can start both timers at the same moment, before putting the egg in the water. When the 3-minute timer ends, put the egg in. This leaves 2 minutes on the 5-minute timer, assuming both timers are relatively accurate. When the 5-minute timer ends, re-set it again for 5 minutes, and you will have your 7 minute egg when the timer ends.

you flip both timers (with all of the sand on one side) and once the five minute timer runs out the first time, you flip the five minute timer.

If you have two hourglasses one four minute timer and one seven minute timer how can you measure nine minutes?
Start both timers, when the four minute timer is done, there will be 3 minutes of sand left in the top of the seven minute timer.Restart the four minute timer, while letting the remaining (3 minutes) of sand to drop from the 7 minute timer. (this is your 1st 3 minutes of your nine minute measurement)When the 7 minute timer is done the 4 minute timer will now have 3 minutes of sand in the bottom. Flip the 4 minute timer (when this runs it will be your second 3 minutes of time). At the same time flip the 7 minute timer.When the 3 minutes of sand run on the 4 minute timer, restart the 7 minute timer by this time 3 minutes worth of sand will have gone to the bottom of the timer, resetting it will give you the last 3 minutes of sand for you last 3 minutes of time measuring the 9 nine minutes.

With a seven minuet and a four minuet egg timer How do you boil an egg for nine minuets?
Use the fact that 4 and 7 have no common prime factors. If you run both timers at the same time, restarting each one whenever it rings, then sooner or later the seven-minute timer will go off two minutes after the four-minute timer did - and then you're in business. In detail: m0: start both timers m4: timer 4 rings, restart it m7: timer 7 rings, restart it m8: timer 4 rings, restart it m12: timer 4 rings, start cooking the egg m14: timer 7 rings, restart it m21: timer 7 rings, take out the egg. The egg went in at minute 12 and came out at minute 21 - nine minutes of cooking. This works because the 7-minute timer rang two minutes after the 4-minute timer did; the seven-minute timer times the last stretch. You can also make the 4-minute timer time the last stretch, and this is actually quicker (I just realized): m0: start both timers m4: timer 4 rings, restart it m7: timer 7 rings, put in the egg m8: timer 4 rings, restart it m12: timer 4 rings, restart it m16: timer 4 rings, take out the egg The egg went in at minute 7 and came out at minute 16, which means it cooked for nine minutes.
