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.

Then it takes twice as much time, or half as much time, respectively, to cover it, provided that the speed never changes.
a) doubled b) tripled c) doubled (assuming the engine is used to bring it back to the same speed) d) quadrupled e) halved
One half is greater than one quarter.
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.
The world population doubled twice between 1800 and 2020 due to advancements in medicine, agriculture, and technology. The first doubling occurred between 1800 and 1927, and the second doubling happened between 1927 and 1974. This rapid population growth has led to various challenges such as resource scarcity, environmental degradation, and social inequality.
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.
