What is Division?
Division is one of the four basic operations in arithmetic (mathematics) apart from addition(+), subtraction (-), and multiplication (×).
Division means splitting into equal parts or groups. It's the result of fair sharing.
For example;
NOTE THE FOLLOWING;
In division we have;
Dividend which is the number to be divided by the divisor.
Divisor is the number we use to divide another Number which we call dividend.
The answer we get after dividing dividend by the divisor is called quotient
In division the rule is;
Divide into
Multiply
Subtract
Bring down
Place the decimal point directly above the decimal point in the dividend, so it lines up with the answer.
Therefore; if Kamau has 7.5kg of sugar to share among his 5 siblings, each sibling will get?
It would be:-
Multiply the quotient by the divisor to get the dividend and to confirm if your answer is correct.
1.5kg × 5
1.5 (quotient)
× 5 (divisor)
7.5 (dividend)
Work out the following
Example 1.
Ruth has Shs. 24.50 to share between her two sons. How much will each son get?
Solution;
Example 2.
Divide 9.396 by 9
9.396 is the dividend while 9 is the divisor.
Remember to add zero(0) in case there is a remainder to enable you divide easily
Example 3.
5.76\8
You can also remove the decimal point by multiplying the dividend and the divisor by multiples of 10.e.g by 10, 100, or 1000 depending on the number of decimal places in the dividend or divisor
5.76 has two decimal places so we multiply by 100 to remove the decimal point
Remember what is done to dividend should also be done to the divisor.
Exercise

1.2.495 divide by 5
2.23.4 divide by 8
3.12.72 divide by 6
