Compound bar charts: big scales and drawing one worksheet: Answers and working
Part A: Working out and filling in
1. 9000 visitors
Find the male bars from the key and what a line stands for, then count the lines up to the top of July's bar.
July's male bar reaches line 9, and a line is 1,000: 9 × 1,000 = 9,000.
2. 7000 visitors
Find the female bars from the key and what a line stands for, then count the lines up to the top of February's bar.
February's female bar reaches line 7, and a line is 1,000: 7 × 1,000 = 7,000 visitors.
3. 40000 visitors
Find the male bars from the key and what a line stands for, then count the lines up to the top of November's bar.
November's male bar reaches line 8, and a line is 5,000: 8 × 5,000 = 40,000.
4. 15000 visitors
Find the female bars from the key and what a line stands for, then count the lines up to the top of March's bar.
March's female bar reaches line 3, and a line is 5,000: 3 × 5,000 = 15,000 visitors.
5. 20000 visitors
Find the female bars from the key and what a line stands for, then count the lines up to the top of May's bar.
May's female bar reaches line 4, and a line is 5,000: 4 × 5,000 = 20,000 visitors.
6. 50000 dollars
One of September's bars stops halfway between lines, so count half a line. Count the gap in lines first, then multiply by what a line is.
In September Shop B's bar stops halfway between lines: 1.5 lines, 1.5 × 20,000. Count the gap in lines, then multiply: 50,000 dollars.
7. 2600000 visitors
Use the key to pick out only this year's four bars. Add up their lines, then multiply by what a line stands for.
Only this year's four bars: 26 lines in all, 100,000 each: 26 × 100,000 = 2,600,000.
8. 35000 dollars
One of November's bars stops halfway between lines, so count half a line. Count the gap in lines first, then multiply by what a line is.
In November Shop B's bar stops halfway between lines: 8.5 lines, 8.5 × 10,000. Count the gap in lines, then multiply: 35,000 dollars.
9. 15 lines
Round 15,491 to the nearest thousand first: look at its hundreds digit.
The hundreds digit is 4, so to the nearest thousand it is about 15 thousands: 15 lines.
10. 20 lines
Round 19,522 to the nearest thousand first: look at its hundreds digit.
The hundreds digit is 5, so to the nearest thousand it is about 20 thousands: 20 lines.
11. 4 lines
Round 4,423 to the nearest thousand first: look at its hundreds digit.
The hundreds digit is 4, so to the nearest thousand it is about 4 thousands: 4 lines.
Part B: Choose, or true or false
12. C. April
Every line stands for the same amount, so no need to read each bar: just count how many lines apart each month's two bars are.
Every line stands for the same amount, so compare the gaps in lines: April's is 5, the most.
Part C: Word problems
Marking: 2 for the working, 1 for the answer, 1 for the sentence.
13. 10000 visitors
Use the key to tell last year from this year, count how many lines apart July's two bars are, then multiply.
This July: 6 lines; last: 4. The gap is 6 − 4 lines at 5,000: 10,000.
14. D. July
Every line stands for the same amount, so just add each month's two bars in lines and compare.
Add each month's two bars in lines: July has 17, the most.
15. 2 times
Every line stands for the same amount, so just count the lines in June's overseas and local bars.
Overseas 4 lines, local 2, each line the same: 4 ÷ 2 = 2 times.
16. 10000 borrowings
Count the lines in June's two bars, add them, then multiply by what a line stands for.
June's two bars: 6 + 4 = 10 lines, 1,000 each: 10,000.
17. 220000 dollars
Add up the lines in Shop A's four bars and in Shop B's four bars first, then find the gap.
Shop A: 8 + 5 + 6 + 8 lines; Shop B: 8 + 2 + 5 + 1. 11 lines apart: 11 × 20,000 = 220,000.
18. 2 times
Every line stands for the same amount, so just count the lines in August's overseas and local bars.
Overseas 10 lines, local 5, each line the same: 10 ÷ 5 = 2 times.
