first you take the number and then you find the closest number to the other number and then you keep doing that but you keep adding Leslie Rose and then you add the number that you had put on the side for to get the right answer of the number you needed that and that is the answer
for this question, I am going to use the example 249÷20.
Find 249 ÷ 20.
Estimate: 240 ÷ 20 = 12
Divide the tens.
1
____
20)249 Divide: 24 ÷ 20 = 1
- 20 Multiply: 1 x 20 = 20
4 Subtract: 24 - 20 = 4
Compare: 4 < 20
Bring down the ones. Divide the ones.
12 R9
_____
20)249
- 20V
49 Divide: 49 ÷ 20 = 2
- 40 Multiply: 2 x 20 = 40
9 Subtract: 49 - 40 = 9
Compare: 9 < 20
The answer is reasonable since it is close to the estimate, 12.
Check.
