2. Divide 48 into 7 parts on average. How much is each part? The formula is ().

3. In a formula with a remainder, if the remainder is 7, then the minimum divisor should be (); If the divisor is 7, then the remainder should be ().

4. A boat can take up to 3 people, so 14 people need at least () boats to cross the river.

5, a dress order 5 buttons, 18 buttons can order () clothes.

6. How much can I put in ()?

7 and 35 have at most () eights and 48 has at most () fives.

8、39÷( ) = 5……4,( )÷7 = 2……2

Second, I am a little judge. (Mark "√" in the right picture and "×" in the wrong question. )

1、36÷4 = 8……4 ( )

2. In the subtraction formula, the difference must be less than the minuend. ( )

3. When using the remainder to calculate the division, if the dividend is relatively small, we can write the number directly. ( )

4. When calculating the division with remainder, we usually try to find the quotient by oral judgment. ( )

5,64 ÷ 9 can be calculated like this. ( )

Third, I will choose.

1, in the following calculation, the correct one is ().

a、59÷8 = 7……2 B、68÷7 = 8…… 12 C、50÷7 = 7…… 1

2. When calculating division with remainder, pay attention to ().

A, the remainder is larger than the divisor by b, the remainder is smaller than the divisor by c, and the remainder is larger than the divisor.

3. Give 25 peaches to 3 monkeys. How much can each monkey get? How much is left? The correct calculation is ().

A, 25÷3 = 8... 1 B, 25 ÷ 3 = 8 (only) ... 1 (piece)

C, 25÷3 = 8 (pieces) ... 1 (pieces)

4. Among the following numbers, the one that has no remainder after being divided by 6 is ().

a、 14 B、24 C、34

5. For division with a divisor of 8, the remainder may be ().

a、7、6、5、4、3、2、 1

b、7、6、5、4、3、2、 1、0

c、8、7、6、5、4、3、2、 1

6. On the physical education class, the teacher asked a group of students to count down with "1 2" in turn, and Xiaoxiao ranked at 17, which should be reported ().

A, uncertain b, 2 C, 1

Fourth, I can calculate.

1, a number written directly.

9×6 = 8×7 = 45÷9 = 80-22 = 64÷8 =

37÷4 = 48÷5 = 68÷8 = 30÷7 =

2. Column vertical calculation.

52÷6 66÷8 5 1÷8 50÷6

5. Problems in life.
