Answer Key
Pie charts
Section A: Quick Questions
Q1
B — How each part makes up a whole
Q2
A — One part of the whole
Q3
B — 100%
Q4
A — A quarter of the circle
Q5
A — How a class of 24 students travel to school
Section B: Match the Pairs
Q1
pie chart → A circle chart split into slices that shows how each part makes up a whole
Q2
25% → A slice that is one quarter of the whole pie
Q3
All the slices of a pie chart add up to the whole, which is 100% → 40% + 35% + 25% = 100%
Q4
Use a pie chart to show parts of one whole, like how a class's favourite pets are shared out → Pie chart: Dogs 50%, Cats 30%, Fish 20%
Q5
Pie chart slices: 50%, 40%, 30% → The slices add up to 120%, but a pie chart must add up to 100%. Change a value, for example to 50%, 30%, 20%.
Q6
Pie chart of daily temperatures: Mon 22, Tue 25, Wed 19, Thu 28, Fri 24 → Temperatures are not parts of a whole, so a pie chart is the wrong choice. Use a line chart or column chart instead.
Section C: Definitions
Q1
pie chart — A circle chart split into slices. Each slice shows how big one part is compared with the whole, often as a percentage. All the slices add up to 100%.Section D: Fill in the Blanks
Q1
=B2/SUM(B2:B5)Q2
percent = part / total * 100Q3
slice1 + slice2 + slice3 = 100%Q4
Parts of a whole: use a pie chartQ5
=B2/B6*100Section E: Spot the Error
Q1
B — The slices of a pie chart must add up to 100%. 60% + 30% + 20% is 110%, so Dogs should be 50%.
Q2
C — 5 out of 20 students is 25%, not 50%. Cats should be 25%.
Q3
B — A pie chart shows parts of a whole, not change over time. A line chart is the better choice, so line 2 should say line chart.
Q4
C — The size of a slice matches the size of the part. A smaller value gets a smaller slice.
Q5
D — Each slice needs its own colour so you can tell the parts apart. It should be one colour per slice.
