Draw the circle and mark the fractional part 3 8 and colour it also.

The given fractional part is 3 8 . We need to draw the circle and mark the fractional part 3 8 and colour it also. We know that, the central angle of circle is 360 ° . Then, 3 8 of 360 ° is 3 8 × 360 ° = 3 × 45 ° = 135 ° Now, using protractor mark 135 ° on circle. That is, Now, colour 3 8 135 ° fractional part of a circle. That is, Here, the green colour part represents the numerator of a fraction. Hence, the fractional part 3 8 is marked and coloured on the circles above.

Draw a circle and mark the fractional part 2 5 and colour it also.

The given fractional part is 2 5 . We need to draw the circle and mark the fractional part 2 5 and colour it also. We know that, the central angle of circle is 360 ° . Then, 2 5 of 360 ° is 2 5 × 360 ° = 2 × 72 ° = 144 ° Now, using protractor mark 144 ° on circle. That is, Now, colour 2 5 144 ° fractional part of a circle. That is, Here, the red colour part represents the numerator of a fraction. Hence, the fractional part 2 5 is marked and coloured on the circles above.

Draw circle and mark the fractional part 4 9 and colour it also.

The given fractional part is 4 9 . We need to draw the circle and mark the fractional part 4 9 and colour it also. We know that, the central angle of circle is 360 ° . Then, 4 9 of 360 ° is 4 9 × 360 ° = 4 × 40 ° = 160 ° Now, using protractor mark 160 ° on circle. That is, Now, colour 4 9 160 ° fractional part of a circle. That is, Here, the blue colour part represents the numerator of a fraction and the whole circle represents the denominator. Hence, the fractional part 4 6 is marked and coloured on the circles above.
