  • Question 1

What fraction of the pie chart is shaded orange?

PIe chart

CORRECT ANSWER
1/5
EDDIE SAYS
We know that the orange section is 20% of the pie. 20% = 20/100 = 1/5 So 1/5 of the pie is shaded orange.
  • Question 2

What fraction of the pie chart is shaded light blue?

PIe chart

CORRECT ANSWER
1/10
EDDIE SAYS
We know that the light blue section is 10% of the pie. 10% = 10/100 = 1/10 So 1/10 of the pie is shaded light blue.
  • Question 3

 

What fraction of the pie chart is shaded purple?

PIe chart

CORRECT ANSWER
1/20
EDDIE SAYS
We know that the purple section is 5% of the pie. 5% = 5/100 = 1/20 So 1/20 of the pie is shaded purple.
  • Question 4

What fraction of the pie chart is shaded green?

PIe chart

CORRECT ANSWER
11/50
EDDIE SAYS
We know that the green section is 22% of the pie. 22% = 22/100 = 11/50 So 11/50 of the pie is shaded green.
  • Question 5

What fraction of the pie chart is shaded red?

PIe chart

CORRECT ANSWER
9/50
EDDIE SAYS
We know that the red section is 18% of the pie. 18% = 18/100 = 9/50 So 9/50 of the pie is shaded red.
  • Question 6

What fraction of the pie chart is shaded green and red?

PIe chart

CORRECT ANSWER
2/5
EDDIE SAYS
Add the green and red sections together 22% + 18 % = 40% 40% = 40/100 = 2/5 So 2/5 of the pie is shaded green and red.
  • Question 7

What fraction of the pie chart is shaded orange and dark blue?

PIe chart

CORRECT ANSWER
9/20
EDDIE SAYS
Add the orange and dark blue sections together 20% + 25% = 45% 45% = 45/100 = 9/20 So 9/20 of the pie is shaded orange and dark blue.
  • Question 8

What fraction of the pie chart is shaded purple and light blue?

PIe chart

CORRECT ANSWER
3/20
EDDIE SAYS
Add the purple and light blue sections together 5% + 10% = 15% 15% = 15/100 = 3/20 So 3/20 of the pie is shaded purple and light blue.
  • Question 9

What fraction of the pie chart is shaded orange, dark blue and red?

PIe chart

CORRECT ANSWER
63/100
EDDIE SAYS
Add the orange, dark blue and red sections together 20% + 25% + 18% = 63% 63% = 63/100 So 63/100 of the pie is shaded orange, dark blue and red.
