Bài 3: Fraction explanation

Another explanation for fractions.

Hi Starry, let revise fractions.

Look at this fraction, here out of 3 equal parts 2 are selected.

So 2 is a numerator and 3 is denominator.

We read this fraction as 2 upon 3.

Now Starry, look at these paper strip.

This figure is divided into 3 equal parts.

Each part of the 3 equal parts of the whole is 1 upon 3.

So 2 such part is 2 upon 3.

So the coloured part is 2 upon 3 and the uncoloured part is 1 upon 3.

Let us look at another example.

Here 1 whole is divided into 5 equal parts.

So each part equal 1 upon 5. Here 3 such part is 3 upon 5.

So the part with design is 3 upon 5 and the part without design is 2 upon 5.

Isn’t it interesting Starry?

Now observe this.

One whole is divided into 4 parts.

Each coloured part is 1 upon 4. 3 such part equal 3 upon 4.

Look at this one, if each part is 1 upon 11, 5 such part is 5 upon 11.

Look at the next one, if each part is 1upon 13, 6 such part is 6 upon13.

If each part is 1 upon 7, then the four such parts will be 4 upon 7.

Let us revise. Fill the boxes with the proper fraction.

The first one state each part equal 1 upon 3, 2 such parts is (dash). The answer is 2 upon 3.

The second one state that each part is 1 upon 9, 7 such parts is (dash). The answer is 7 upon 9.

The next one tells us that it part equal 1 upon 8, so 5 such parts equal (dash). The answer is 5 upon 8.

Let us do another activity for each fraction.

Name the numerator and denominator. Write the fractions in words.

Answer the first one.

Here the numerator is 3 and denominator is 13 and the fraction is read as three upon thirteen.

Answer the second one here the numerator is 7 and denominator is 9 and the fraction is read as seven upon nine.

Answer the third one.

Here the numerator is 5 and the denominator is 21 and the fraction is read as five upon twenty-one.

And now answer the last one.

Here the numerator is 6 and denominator is 7, the fraction is read as six upon seven.

So, today you have learnt another way of looking at the fractions. Bye
