1. Tailing method: saw a 7-meter-long pipe into 3-meter-long segments, which can be sawed into 7/3=2.3333 ... In theory, only 2 segments can be taken here, which is the tailing method.

2, the method: 8 people go by car, but each car can only take 3 people, according to theory, 8/3=2.666 ... This is ok, but in fact it needs 3 cars, which is a method.

Truncation, that is, the omitted position should be discarded whether it is full or not.

One-in-one method, that is, as long as the omitted position is greater than zero, one digit must be entered.

Practical application of tail removal method and one-step method

1, tailing method

For example, each children's wear needs 1.2m cloth, and the existing cloth is17.6m. How many pieces can such clothes be made?

Solution:17.6÷1.2 =14.66. ...

The result is 14.66 ... If the approximate value is truncated by rounding, it should be 15 pieces. But when it comes to making clothes, we all know that although the remaining cloth can be made into 0.6 pieces, it is not enough to make a piece of cloth, so we can only take the method of removing the tail. that is

17.6 ÷1.2 =14.66 ... ≈14 (pieces)

A: This can make 14 clothes.

2, into the law

Example: A sack can hold 200 Jin of wheat, and at present there are 880 Jin of wheat. How many sacks do you need to pack them all?

When 880 is divided by 200, the quotient is 4, and the remainder is 80, that is, 4 sacks are not enough, and 5 sacks are needed.
