Explanation:
Given to find 560 ÷ 80 we get 560 ÷ 10 ÷ 8,
= 56 ÷ 8 = 7.
Question 2.
630 ÷ 60 = __10 R 3___
Answer:
10 R 3,
Explanation:
630 ÷ 60 = 63 ÷ 6 = 10 R 3,
Question 3.
590 ÷ 30 = __19 R 2___
Answer:
19 R 2,
Explanation:
590 ÷ 30 = 59 ÷ 3 = 19 R 2,
Question 4.
190 ÷ 90 = _2 R 1____
Answer:
2 R 1,
Explanation:
190 ÷ 90 = 19 ÷ 9 = 2 R 1,
Question 5.
360 ÷ 50 = __7 R 1___
Answer:
7 R 1,
Explanation:
360 ÷ 50 = 36 ÷ 5 = 7 R 1,
Divide.
Example
43 ÷ 12
12 rounds to 10.
4 × 10 = 40
The quotient is about 4.
4 × 12 = 48
The estimated quotient is too big. Try 3.
43 ÷ 12 = 3 R 7
Question 6.
98 ÷ 16 = _6 R 2_
Answer: 6 R 2
Explanation:
16 rounds to 20
5 x 20 = 100
The quotient is about 5
5 x 20 = 100
The estimated quotient is ok.
98 ÷ 16 = 6 R 2.
Question 7.
65 ÷ 24 = _2 R 17__
Answer:
24 rounds to 20
3 x 20 = 60
The quotient is about 3
3 x 20 = 60
The estimated quotient is too small, therefore 65 ÷ 24 is 2 R 17.
Question 8.
94 ÷ 37 = _2 R 7__
Answer: 2 R 7
Explanation:
37 rounds to 40
2 x 40 = 80
The quotient is about 2
4 x 20 = 80
The estimated quotient is too small therefore 94 ÷ 37 = 2 R 7.
Divide.
Example
215 ÷ 51
215 rounds to 200.
4 × 50 = 200
The quotient is about 4.
215 ÷ 51 = 4 R 11
Question 9.
362 ÷ 60 = __10 R 2_
Answer: 10 R 2
Explanation:
362 ÷ 60
362 rounds to 360.
6 × 60 = 360
The quotient is about 10.
therefore, 362 ÷ 60 = _10 R 2.
Question 10.
178 ÷ 45 = _3 R 43__
Answer:
3 R 43,
Explanation:
178 ÷ 45,
178 rounds to 200.
45 rounds to 50
4 × 50 = 200
The quotient is about 4.
So 178 ÷ 45 = _3 R 43.
Question 11.
850 ÷ 88 = _9 R 58__
Answer:
9 R 58,
Explanation:
850 ÷ 88
850 rounds to 900.
88 rounds to 90
10 × 90 = 900
The quotient is about 9.
therefore 850 ÷ 88 = 9 R 58.
Question 12.
273 ÷ 59 = _4 R 37__
Answer:
4 R 37,
Explanation:
273 ÷ 59
273 rounds to 300.
59 rounds to 60
5 × 60 = 300
The quotient is about 4.
therefore 273 ÷ 59 = 4 R 37.
Divide.
Example
354 ÷ 14
354 ÷ 14 = 25 R 4
Question 13.
850 ÷ 17 = _50__
Answer:
50,
Explanation:
8 hundreds 5 tens = 85 tens
therefore 850 ÷ 17 = 50.
Question 14.
546 ÷ 25 = _21 R 21__
Answer:
21 R 21,
Explanation:
5 hundreds and 4 tens = 54 tens,
54 tens ÷ 25 = 2 tens R 4,
4 tens 6 ones = 46 ones,
46 ÷ 25 = 1 R 21,
therefore 546 ÷ 25 = 21 R 21.
Question 15.
700 ÷ 28 = _25__
Answer:
25,
Explanation:
7 hundreds and 0 tens = 70 tens
70 tens ÷ 28 = 2 tens R 14
14 tens 0 ones =140 ones
140 ÷ 28 = 5.
therefore 65 ÷ 24 = 2 R 17.
Question 16.
936 ÷ 43 = _21 R 33__
Answer:
21 R 33,
Explanation:
9 hundreds and 3 tens = 93 tens,
93 tens ÷ 43 = 2 tens R 7,
7 tens 6 ones =76 ones
So 76 ÷ 28 = 1 R 33.
