Why Do We Divide

Why Do We Divide?

The division is a method of distributing a group of things into equal parts. … If 3 groups of 4 make 12 in multiplication 12 divided into 3 equal groups give 4 in each group in division. The main goal of the division is to see how many equal groups or how many in each group when sharing fairly.

Why do we divide and multiply?

When we divide we look to separate into equal groups while multiplication involves joining equal groups. … This is because when we multiply two numbers (which we call factors) we get a result that we call a product. If we divide this product by one of the factors we get the other factor as a result.

Where do we use division in real life?

Division can be introduced by considering objects from our daily life like slices of pizza or a bar of chocolate. For example if we divide a pizza into 4 slices we do division. Thus 1 ÷ 4 = 0.25. This means that each piece of the slice of this pizza is 0.25 times the total pizza.

What are we doing when we divide?

60 is called the dividend it is the number being divided by 15. 4 is called the quotient. It is the number of times we must multiply 15 to get 60. In the figure the quotient is the number of equal parts into which the dividend has been divided.

Dividend ÷ Divisor = Quotient
Quotient × Divisor = Dividend
