FRACTIONAL REPRESENTATION A circle is divided into 8 equal parts with 2 parts shaded

in red. What fraction of the circle is shaded?

Red parts – numerator – 2

Total parts – denominator - 8

So the fraction is represented as

Read : two-eighths of the circle is shaded

WHAT FRACTION OF THE CIRCLE IS SHADED?

5 parts are shaded in red

The circle is divided into 8 equal parts

Parts – 5 (red) – numerator

Whole – 8 –denominator

So the fraction is represented as

Read : five-eighths of the circle is shaded8

DRAW YOUR OWN FIGURE

A rectangle divided into 5 equal parts with 2 of the parts shaded in red. Write a fraction for the part that is shaded

Parts – 2 (red) – numerator

Whole – 5 –denominator

So the fraction is represented as

Read : two-fifths of the rectangle is shaded
