How to divide on a number line?
Learn to divide using number line to find the quotient.
We can do repeated subtraction on the number line to find division.
Let us find 15 ÷ 5.
Thus, 15 ÷ 5 = 3
Solved Examples to show Divide on a Number Line:
1. Solve 14 ÷ 7
Solution:
7 is subtracted repeatedly from 14 using the number line
When 7 is subtracted 2 times from 14 in the number line, then we get the remainder zero.
Thus, 7 is subtracted from 14, 2 times.
Hence, 14 ÷ 7 = 2, 2 is the quotient.
2. Divide 40 ÷ 8
Using the number line 8 is subtracted repeatedly from 40
When 8 is subtracted 5 times from 40 in the number line, then we get the remainder zero.
Thus, 8 is subtracted from 40, 5 times.
Hence, 40 ÷ 8 = 5, 5 is the quotient.
3. Solve 24 by 6
Solution:
6 is subtracted repeatedly from 24 using the number line
When 6 is subtracted 4 times from 24 in the number line, then we get the remainder zero.
Thus, 6 can be subtracted from 24, 4 times.
Hence, 24 ÷ 6 = 4, 4 is the quotient.
4. Divide 15 ÷ 3
3 is subtracted repeatedly from 15 using the number line
3 is subtracted from 15, five times in the number line, then we get the remainder zero.
Thus, 3 can be subtracted from 15 five times.
Hence, 15 ÷ 3 = 5, 5 is the quotient.
5. Divide 63 ÷ 9
9 is subtracted repeatedly from 63 using the number line
9 is subtracted from 63, seven times in the number line, then we get the remainder zero.
Thus, 9 can be subtracted from 63 seven times.
Hence, 63 ÷ 9 = 7, 7 is the quotient.
The above examples will help us to solve various division problems on 1-digit number and 2-digit number by a single digit number using number line.
