I'm guessing that the word 'and' refers to addition, so
twice a quarter = 2 * (1/4) = 2/4 = 1/2
quarter doubled is the same = 1/2
so 1/2 + 1/2 = 1 (the first part of the question)
2nd part:
half a half = (1/2) * (1/2) = 1/4
half halved = (1/2)/2 = 1/4
so 1/4 + 1/4 = 1/2
so the first part 'twice a quarter and a quarter doubled'is greater, because 1 > (1/2)
One half is greater than one quarter.
17 doubled once is 34doubled again is 68.so 17 doubled twice is 68.
Since the number is halved when reduced by 13, then the number must be twice 13 = 26.

A coin that has been stamped twice.
One half is greater than one quarter.
If the distance is doubled, the gravitational force between two objects decreases by a factor of 4. If the distance is halved, the gravitational force increases by a factor of 4. This relationship is described by the inverse-square law of gravitation.
17 doubled once is 34doubled again is 68.so 17 doubled twice is 68.
2/4 is twice as much as 1/4
Since the number is halved when reduced by 13, then the number must be twice 13 = 26.
doubled
The population of the world is estimated to have doubled twice during the 20th century. The first time it doubled was between 1927 and 1960, and the second time was between 1960 and 1999.
a) doubled b) tripled c) doubled (assuming the engine is used to bring it back to the same speed) d) quadrupled e) halved
It means "twice as much", i.e "doubled".

Acceleration is doubled. F = ma, where m is mass and a is acceleration. If mass is halved, acceleration is changed by a related quantity, X in this equation. F = (1/2m)(Xa) The coefficients before mass and accelerations have to equal 1 if force stays the same, so... 1/2*X=1 X = 2 therefore, acceleration is doubled.
If you do work on an object in half the time, your power output is twice as high. Power is the rate at which work is done, so if the time to do the work is halved, the power output is doubled to maintain the same amount of work done per unit time.
