How to do a word problem? As follows, how to do the application problem?

A kilogram of bananas is cheaper than a kilogram of apples"That is to say, the price per kilogram of apples minus the price of each kilogram of bananas is equal to yuan, yuan).

Yuan) 3 + 5 = 8 (kg).

Yuan) Yuan) A: Yuan per kilogram of bananas.

Assuming that all bananas are bananas, the total price should be the difference between catties of apples) = yuan.

Banana: Yuan 8 = Yuan.

Apple: Yuan + Yuan.

Banana Equation: (Yuan.

Solution: Let each kilogram of banana be x yuan, then each kilogram of apple (x+ yuan, have: 3x+5*(x+, solution: x=

Solution: If the banana is $x, then the apple is $+.

3x+5（x+

3x+5x+6=

8x=8x=

x = meta.

Let's take $x per kilogram of bananas.

Then the columnable equation: 3x + x+

The result of solving the equation is: x=

Then bananas are dollars per kilogram.

If x yuan per kilogram of bananas, then there is (x + yuan) per kilogram of apples.

According to the question, there is 3x+5*(x+, the solution is x=

then per kilogram of bananas.

I'm sweating, I've graduated from college, and now I'm dripping ...... kids

Bananas are $x, apples are $Y.

3x+5y=

y-x=x=more sweat drops four, I still did it wrong, when I didn't exist at it, tears flowed.

18 pcs. A: In December, an average of 18 sets of tea sets were sold per day.

The title is not clear, guess: a shopping mall sold an average of 16 sets of tea sets per day in the first half of December (15 days); In the second half of the month (16 days), an average of 20 sets of tea sets were sold per day. How many sets of tea sets are sold per day on average in December? (The number is kept as an integer).

16 15 + 20 16) (15 + 16) = 560 31 18 (sets).

Quantity relationship: average sales volume per day in December = total sales volume in December Total number of days in December.

I didn't understand what you meant, no matter how anxious you are, you have to make it clear......

There are 4 tons of flour in the canteen of the machine tool factory, and tons are used in 7 days According to this calculation, how much more can this flour be used?

The construction site needs a total of tons of water, a total of 3 hours to transport a total of tons of cement, and the rest to be transported in 4 hours How many tons per hour on average? How much more is the remaining average hourly than the previous 3 hours?

Average hourly shipment: (tons).

Shipped more than the previous 3 hours on average per hour: tons).

A and B two road construction teams jointly build a kilometer-long road, A repairs kilometers every day, more kilometers than B, after the two teams repair 12 days together, Team B repairs alone, how many days does it take to complete?

18t coal was transported from the canteen, which was originally burned every day, and after 15 days of burning, the demand increased, and it was burned every day, how many days would it take to burn it?

A car drives from A to B to transport a batch of goods, driving 84km, at this speed, the car is shared between the two places, find how many kilometers apart between A and B?

84 km).

According to the inscription column, it is calculated as follows:

Yuan answer: A pencil is yuan.

First read the question and see what the question is asking? It's the ** of the movable pencil that is asked!! So let's go to the question to find the conditions for a movable pencil, a fountain pen, which is more expensive than a movable pencil, which is a useful condition.

A movable pencil is cheaper than a ballpoint pen, this condition is useless in the current topic, we according to the useful conditions of the pen is more expensive than the movable pencil, then it means that the pencil is cheaper than the pen, we know that the pen's ** is yuan, then the pencil's ** comes out.

Yuan: A movable pencil is Yuan.

1.Get off the quarter, and leave three-quarters. The 300 people who got on the bus corresponded to the difference between nine-tenths and three-quarters of those people. So the car was original:

300 [(9 10)-(3 4)] = 2000 (people) The idea is: find the corresponding parts, divide them to get the total. If you can't think clearly, draw a line diagram.

2.It turns out that all the books minus the 25 represent the literary books 2 plus one-ninth of the science books that were borrowed. Take the original number of all the books and subtract this, which means that you have twice the original science and technology books minus one ninth of the science and technology books.

So the original science and technology book:

740 2-(740-25)] 2-(1 9)]=405 (book) So the original literary book: 740-405=335 (book) Idea: Or find the correspondence between "how many copies" and "fractions", and divide them.

When looking for the correspondence between the two, draw a line segment diagram. If you have any specific skills to find a correspondent, ask your elementary school teacher......It's been so many years since I graduated from elementary school, and I still remember these things, and it's not easy to write like this......Give me a little more ......

1.Set up the original x people. 3 4x+300=9 10xSolution:x=2000

2.There are x books on literature and art, and 740-x books on science and technology. (740-x)x8 9-x=25 Solution: x=335

There are 335 literary books and 405 scientific and technological books.
