What fraction is shaded?

This shape has been divided into equal parts. And we can see that each part is a triangle. All the triangles are the same size. To help us find the fraction that’s shaded, the first thing we need to do is to count the number of parts that the shape has been split into. One, two, three, four, five. When we write a fraction, the total number of equal parts is known as the denominator. It’s the bottom number in our fraction.

Because this shape has been divided into five equal parts, we can write the number five as our denominator. So, we can see that the answer to our question, the shaded fraction, is going to be a number of fifth. Now, all we need to do is to complete the numerator, the top number in the fraction. This is the number of chosen parts, the number of parts that we’re talking about. And in this question, the number of parts that we’re talking about are the shaded parts.

In other words, how many out of five triangles have been shaded? We can see that two out of five triangles have been shaded. And so, we know our numerator is going to be the number two. Our shape has been split into five equal parts, and two of those parts have been shaded. And so, if two out of five parts are shaded, we can write the shaded fraction as two-fifths.
