Locate salt and vinegar along the x-axis labeled type of crisp. Follow the bar upwards for salt and vinegar and then look at the y-axis, which will show you how many children chose salt and vinegar. The bar is in between 8 and 10, which means that 9 children chose salt and vinegar.

To find out how many children took the survey, add all of the numbers for each of the crisps: 12 + 9 + 2 + 4 + 7 + 1 + 0 + 2 + 3 = 40. Excellent work!

Question 8

Use this bar chart to answer the question.

What fraction of the group surveyed chose Ready Salted?

Bar chart crisps

CORRECT ANSWER

12/40

EDDIE SAYS

A fraction is the part of the whole and earlier we found out that 40 children took the survey. So the fraction of the group that chose ready salted is 12/40. Amazing work!

ANSWERS

Question 9

Use this bar chart to answer the question.

Which flavour/flavours were chosen by exactly one tenth of the group surveyed?

Bar chart crisps

CORRECT ANSWER

Pickled Onion

EDDIE SAYS

This is a tricky question! Make sure to think about equivalent fractions. Here are the fractions for each crisp and equivalent fractions if they have one: ready salted 12/40 = 3/10, salt and vinegar 9/40, cheese and onion 2/40 = 1/20, pickled onion 4/40 = 1/10, chicken 7/40, prawn cocktail 1/40, smoky bacon 0/40, roast beef 2/40 = 1/20, pizza 3/40. So pickled onion had 1/10 of the choices.

ANSWERS

Question 10

Use this bar chart to answer the question.

What percentage of the group chose Ready Salted, Chicken or Prawn Cocktail?

Bar chart crisps

CORRECT ANSWER

50%

EDDIE SAYS

To solve this problem, you need to add 12 + 7 + 1 = 20. Now that you have the total for the three crisps, you need to make a fraction for part of the whole, which is 20 out of 40 or 20/40. So the percentage is 50% or half. Well done for working through these questions!
