Recognising Fractions

Look over this list of fractions. We learnt these fractions in Years 2 and 3, and you should learn to recognise them quickly just the way you recognise the numbers 1 to 10. How would you write the fraction that represents each circle?

fractions

You know that a fraction represents a portion of a whole. It can be a part of one thing or a part of a group of things. The bottom number of a fraction, called the denominator, tells how many equal parts the whole was divided into. The top number of a fraction, called the numerator, tells how many of the equal parts you are talking about. For example, if you have an apple and you slice it in four quarters, you have made four equal portions. Each portion represents 1/4, or one out of the four equal parts of the apple.

In the fraction 4/8, 4 is the numerator and 8 is the denominator.

In the fraction 9/10, what is the numerator and what is the denominator?

In the fraction 5/7, what is the numerator and what is the denominator?

fractions of paintbrushes

How many paintbrushes in this picture are green? How many paintbrushes are there total? What fraction of the paintbrushes are green?

Now, how many paintbrushes in this picture are yellow? How many paintbrushes are there total? What fraction of the paintbrushes are yellow?

3/5 of the paintbrushes are green. 3 is the numerator and 5 is the denominator, and we are talking about 3 of the 5 paintbrushes.

2/5 of the paintbrushes are yellow. 2 is the numerator and 5 is the denominator, and we are talking about 2 of the 5 paintbrushes.
