Sixth grade math problems, do well to add

A section of the road is 5km, which is repaired in 8 days, and the average is repaired (5 8) km per day, and the road is repaired every day (1 8).

Let's make up another question like this.

Xiao Ming ate a box of sugar, a total of 700 grams, and ate it for 6 days, eating an average of (700 6) grams per day, and eating (1 6) of this box of sugar every day

The terracotta warriors and horses are known as one of the eight wonders of the world, of which there are 3,200 infantry figurines, which is 1,600 pieces less than the sum of other arms, and the sum of other arms is a fraction of more than the number of infantry figurines? (to be calculated).

It can be known that there are 1,600 more pieces of other arms than infantry figurines, and 1,600 is divided by 3,200 to get one-half.

End, plus points

A section of the road is 5km, which is repaired in 8 days, and the average ( ) km is repaired every day, and the ( ) of this section of the road is repaired every day

A building is 50 meters high and built in 10 days. On average, ( ) meters are built every day, and ( ) other arms = 3200 + 1600 = 4800 3200 4800 = 2 3 The sum of other arms is 2 3 more than the number of infantry figurines

Eighth.

3200 + 1600 = 4800 pieces 3200 divided by 4800 = two-thirds.

For example, if you want to make 100 parts, Master Zhang will finish them all in 10 days, making an average of ( ) parts per day, and making ( ) of the total number of parts per day

The sum of the other arms is 1 2 more than the number of infantry figurines.

1 If the elder brother has x cards, then the younger brother has 3x 4 cards, x+3x 4=105

x = 60 brother 60 cards, location 45 cards.

That is, this piece of land has 4 hectares.

10,000 yuan = 7,500 yuan.

Therefore, the business tax should be paid 7,500 yuan this month.

18 black rabbits.

1 brother 105 (1 + 3 4) = 60 brother 105-60 = 45

2 7 3 (1-5 12) = 4 hectares.

3 15*5%=10,000 yuan.

4 Black rabbits 24*3 4=18.

1.Let my brother have x stamps, x+3x4=105 and x=602The land is set up with x hectares, and 5x 12 + 7 3 = x solution gives x = 43 15*5%=7500

4.Number of black rabbits = 24 * 3 4 = 18, number of all rabbits = 18 + 24 = 42

1. The younger brother's is 45, and the elder brother's is 60

Hectare. yuan, or you can write ten thousand yuan.

Only! ...Why is the question of the sixth grade so simple ...... this time?

1.According to the number of copies, it is solved like this: Brother and brother have a total of 4 + 3 = 7 copies, 105 7 = 15 sheets, this is one copy, the elder brother has 4 copies, that is, 15 * 4 = 60 copies, and the younger brother has 3 copies, which is 15 * 3 = 45 copies.

2.Seven-thirds (1-5 out of 12) if you're in sixth grade, you should understand that you end up with seven-two-hectare.

10,000 yuan = 7,500 yuan.

4.How many black rabbits are there? 24 * three-quarters = 18 pcs. It's so easy. It's not a bit of a stretch. Hehe.

1. If the number of philatelic records of the elder brother is x, then the equation of the philatelic number of the younger brother is 3 4x sheets as x+3 4x=105, x=60, 3 4x=45, so the philatelic number of the elder brother is 60 sheets, and the number of philatelic numbers of the younger brother is 45 sheets.

2. If there are x hectares in this land, then 5 12x hectares have been plowed in the morning, and the equation is listed as 5 12x+7 3=x, x=4

So the land has 4 hectares.

This month's tax payment is 10,000 yuan.

4. You can ask, how many black rabbits are there? Or how many rabbits there are in total.

The answer is that there are 18 black rabbits, and there are 42 rabbits in total.

1. The elder brother and the younger brother collected a total of 105 stamps, and the number of stamps collected by the younger brother was three-quarters of that of the elder brother. How many stamps do you collect?

Answer: 60 for the elder brother and 45 for the younger brother.

2. A farm tractor ploughs a piece of land in one day. Five-twelves of the field was ploughed in the morning and seven-thirds of the hectares in the afternoon. How many hectares is there in this plot? A: 4 hectares.

3. The turnover of a large hotel in a month is 150,000 yuan. If you pay business tax at 5% of your turnover, how much business tax should you pay this month? A: 7500 yuan.

4. There are 24 white rabbits, and the number of black rabbits is three-quarters of that of white rabbits, Answer: 18 black rabbits.
