Which figures have one-quarter shaded?

We’re shown four different shapes. a is an oval shape. Shape b looks like a capital letter H. c is a circle and d is a square. And each of these shapes has been shaded. Part of each shape has been coloured. We have to pick the shapes which have one-quarter shaded. We know we’re looking for more than one shape because the question asks us to find the figures. The “s” on the end of this word tells us we’re looking for more than one. Let’s start by looking at shape a.

The orange line shows us where the shape was cut into two-halves and the shape was cut into half again. If we halve and then halve again, we get quarters. Now, shape a has four equal parts. We call each part a quarter. And we can see that one of those quarters has been shaded. This is one of the figures which has a quarter shaded. Now, let’s look more closely at shape b.

This line shows whether shape was cut into two-halves. Then, one of the halves was cut into half again. When we halve a shape, then halve it again, we get a quarter. And we can see that one of the quarters has been shaded orange. Shape b also has a quarter shaded. Shape c has been halved, halved again to make quarters. And it’s been halved again to make eighths. Although this circle has been cut into eight equal parts, if we look more closely at the blue lines, we can see that two of those eight parts make a quarter. So shape c also has a quarter shaded. Figure d or shape d has been cut into half and half again. And one-quarter has been shaded blue. So Shape d also has a quarter shaded.

All of the figures have a quarter shaded. Figure a, b, c, and d all have one-quarter shaded. So the answer to the question which figures have one-quarter shaded is a, b, c, and d. All of the figures have one-quarter shaded.
