This is a job for Boyle's Law!
Mr. Robert Boyle, eminent chemist who died a very long time ago, discovered that for a given mass of gas at a constant temperature, volume and pressure have an inverse relationship. Or to put it another way, if you have a number of grams of gas in a 1-liter bottle at 2000 millibars and you transfer all of it to a 2-liter bottle, the pressure will be reduced to 1000 millibars.
The formula is
P1 x V1 = P2 x V2
At sea level the air pressure is roughly 1000 millibars, and we know we have 7 liters of air are in the balloon. Multiply 7 (the volume) x 1000 (the pressure) and you get 7000. Divide that number by 9 and you've got it.
******************************************************************
Normal commercial flights have a cabin pressure equal to 7,000 ft ASL. That's just enough to prevent passengers from getting altitude sickness, and the lower the cabin pressure the less stress on airframe. Just trivia for what it's worth.

What happens to a balloon when pressure becomes less?
When the internal pressure in a balloon falls, the balloon get smaller and less buoyant.
What happens to a balloon's pressure when put into the fridge?
it dies
What happens to the atmospheric pressure acting on the balloon as the balloon rises?
due to pressure inside the balloon, will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
What happens to the pressure of the air outside of the balloon as it goes higher?
The pressure inside the balloon will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
What happens to a balloon if you keep blowing air into it?
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature?
assuming the balloon is closed, the air pressure would double
What happens to a balloon put in a hyperbaric chamber where pressure is increased?
It collaspses.
What happens to the hot air balloon when it reaches an altitude of 10000 meters?
the air pressure outside of the balloon decreases.
If a balloon is rubbed vigorously what happens to the pressure of the air inside the balloon if the volume remains constant?
if vigorous enough to create heat the balloon will expand.
What happens to a balloon on a fine day?
If it's a light balloon, it keeps going up, into thinner and thinner atmosphere, until the pressure inside the balloon is so much greater that the pressure outsize , and then it pops.
What happens to the pressure inside of a balloon as it floats higher and higher?
The atmospheric pressure go on falling. So the pressure in the balloon. It takes lot of height to get the pressure reduced. I mean, the reduction in the pressure can not be easily measured for short height.
What happens when your airplane takes off from an airstrip on the ground and rises 30000 feet into the sky what happens to the air pressure on the outside of the airplane?
Atmospheric pressure is caused by the weight of air above the measurement point. At 30,000 feet in the sky, the air pressure on the outside of the airplane will be much lower than it was nearer the ground.
