Kindergarten Mathematics Problem 2 ^ ()


First teach and look up the number, then use the real object to teach and look up the number, and then identify the number



The kindergarten will give a basket of apples to the children. If five apples are given to each of the children in the large class, there will be six apples missing. If four apples are given to each of the children in the small class, there will be four apples left. It is known that the large class has two apples less than the small class. How many apples are there in this basket______ One


If there are 4 apples per person in the big class, the rest is 2 × 4 + 4 = 12; the number of big friends is 12 + 6 ^ (5-4), = 18 ^ 1, = 18; the total number of apples is 18 × 5-6 = 84; a: there are 84 apples in this basket



The kindergarten bought a batch of apples. If they were given to the children in the big and small classes, no one could get six on average
The average person can get 10. If you only give it to the small class, how many can you get? (use the knowledge of common multiple and common factor to answer, this is connected with the above.) the more ways, the better,


If there are x people in the large class, there will be a total of 10x apples. If there are 10x / 6-x people in the small class, only the small class can be allocated. The number of apples that each person can get is 10x / (10x / 6-x) = 15



If a batch of apples are distributed to the children in two classes, each of them will get 6 apples on average. If they are only distributed to the children in the big class, each of them will get 10 apples on average. If they are only distributed to the children in the small class, how many apples can each of them get?


1 △ (16 − 110), = 1 △ 115, = 15 (apples); a: only for small classes, each person can get 15 apples

60 multiplication problems (to multiply 3 digits by 1 digit)
Wrong
It's two digits by one


3 x 300 = 3 x 301 = 3 x 302 = 3 x 303 = 3 x 304 = 3 x 305 = 3 x 306 = 3 x 307 = 3 x 308 = 3 x 309 = 3 x 310 = 3 x 311 = 3 x 312 = 3 x 313 = 3 x 314 = 3 x 315 = 3 x 316 = 3 x 317 = 3 x 318 = 3 x 319 = ...



There are 230 calculation questions (about 40 can be repeated) and 46 application questions (about 5 can be repeated)
What I want is 3 / 2 + 2 / 1, it's better to be simple. Give 50 points, I'll give more points, ha ha. Don't take off the form, just add and subtract, don't multiply and divide, that's all,
I can't do it. 200





Given that x is an integer and 4 / x-3 + 2 / 3-x is an integer, find the sum of all the values of X that meet the conditions


4 / x-3 + 2 / 3-x=2/x-3
Because it's an integer
x-3=+-1,+-2
x=4
x=2
x=5
x=1
1+2+4+5=12



The two purchasers, a and B, went to the same feed company twice to buy the feed. The price of the feed changed slightly, and the two purchasers' purchasing methods were also different. Among them, a purchased 1000 kg each time, and B spent 800 yuan each time, no matter how much feed they bought. Suppose the unit price of the feed purchased twice was m yuan / kg and N yuan / kg respectively (m, n are positive numbers, and m ≠ n) What is the average unit price of feed purchased by B? Which one is lower?
