【What does mean that being divided by a fraction?】

For example,let's suppose there were circular cake or pizza which are easy to divide equally.If divided the pizza into four,there will be four pieces of the pizza.Its each size is a quarter.🍕

In short,one divided by a quarter is four.💡

It means the next one.If dividing the pizza into four pieces,we'll give each of four people each of four pieces of pizza.🍕

We can make the question,applying the sentence above like the next one.💡

There are circular three pizzas.They are the same size.We divided each of them into four equal parts.Then we put each three pieces on a plate.How many plates do we need?☝

If showing a picture of each pizza divided into equally with a calculation,“twelve divided by three is four”, children'll grasp it easily.😃

We are going to add other explanation including an equation of fractions in order to make even elementary school children understand.☝

To be continued.💦
