FlowerTallyRoseDaisyLilyCarnation|||| |||||||||||| ||||

The tally chart shows the number of flowers in a different display.
Antonio says there are exactly twice as many roses as daisies.
Is he correct? Tick a box. Show your working.

How to approach this question

1. Convert the tallies for Rose and Daisy into numbers. Remember that a gate symbol (four vertical lines with a diagonal line through them) represents 5. 2. Write down the number of roses and the number of daisies. 3. Calculate what "twice as many as daisies" would be by multiplying the number of daisies by 2. 4. Compare this result with the actual number of roses. 5. Conclude whether Antonio is correct and tick the appropriate box.

Full Answer

No. Working: Number of roses = 9 Number of daisies = 5 Twice the number of daisies = 2 * 5 = 10. Since 9 is not equal to 10, he is not correct.
First, we need to find the number of roses and daisies from the tally chart. - The tally for Rose is one gate (5) and four single lines (4). So, number of roses = 5 + 4 = 9. - The tally for Daisy is one gate (5). So, number of daisies = 5. Antonio claims there are twice as many roses as daisies. Let's check this: Twice the number of daisies is 2 × 5 = 10. The actual number of roses is 9. Since 9 is not equal to 10, Antonio's statement is incorrect.

Common mistakes

✗ Miscounting the tallies. For example, counting the gate as 4 or 6. ✗ Making a calculation error, e.g., 2 * 5 = 9. ✗ Ticking the correct box but not showing any working.
