Anonymous users2024-02-11Choosing C can first assume that the weight of the pear is 1, and it is known that the apple is one-sixth heavier than the pear, that is to say, the weight of the apple is the weight of the pear plus one-sixth of the weight of the pear, that is, the weight of the apple = 1 + 1 * (1 6) = 7 6
Now considering how many fractions of a pear's weight is lighter than an apple's, it is easy to calculate that a pear is one-sixth lighter than an apple (7 6-1 = 1 6).
The weight of a pear is a fraction lighter than that of an apple, that is, how much does a sixth of a pear account for the total weight of an apple, then just divide one-sixth by seven-sixths of the total weight of the apple, that is: (1 6) divided by (7 6) = 1 7
So choose C

Anonymous users2024-02-10If the weight of the pear is regarded as 1, then the weight of the apple is seven-sixth, and the problem is measured by the weight of the apple, so the weight of the apple is 1, then, the weight of the pear is six-seventh, therefore, the weight of the pear is one-seventh lighter than the apple, this kind of topic mainly depends on who refers to the standard, and the standard is generally set to 1, so as to draw conclusions based on this.

Apples are one-sixth heavier than pears, and if pears are considered as 6 parts, then apples have such 6 + 1 = 7 parts.
Hence the weight of a pear is 1 7 lighter than an apple

Anonymous users2024-02-08Divide pears and apples into six and seven parts respectively, then it is in line with the fact that apples are one-sixth heavier than pears, then the number of parts of pears is six as the denominator, and one-sixth is equal to (the number of parts of apples 7 - the number of parts of pears 6) The number of parts of pears is 6, if you want to find out how much lighter the weight of pears is than apples, you need to use (the number of parts of apples 7 - the number of parts of pears 6) The number of parts of apples is 7, that is, one-seventh.

Anonymous users2024-02-07Apples are one-sixth heavier than pears, which means that pears are lighter (1/7) than apples
In the unit of pears 1, apples account for 1 + 1 6 = 7 6 of pears
Then the weight of pears is lighter than that of apples: 1 6 7 6 = 1 7

Anonymous users2024-02-06Suppose the pear weighs x grams, and the apple weighs one-sixth of the pear, so the apple weighs x 6+x grams.
x 6 + x - x = x 6, i.e. pears weigh x 6 grams less than apples.
Divide the weight of a pear that is lighter than an apple by the weight of an apple to draw the conclusion:
x/6）/（x/6+x）

Anonymous users2024-02-03Draw a picture, you think, apples are one-sixth heavier than pears, pears are six, and one more than six is seven. The apple is seven, the pear is lighter than the apple, and the apple is the unit one, so use the unit one as the denominator, and the difference number as the numerator!

When I was a child, my favorite fruit was oranges, and I had to eat a lot of oranges every year, until I went to college, and everyone advised me to eat less oranges, because it was easy to get angry.
