Weights and measures are used for solving problems in day to day life. One example is when using a recipe. If the recipe is for two persons and you are making it for six, you'll need to know how to increase the amount of ingredients without ruining the meal!
We have a total of 8 sets of quizzes about solving problems. The first four are general, the second four involve money. As usual, they get progressively more difficult. It's important to know how to work with numbers in everyday life, and these quizzes will test your maths skills. It would be a good idea to play them until you have a perfect 10 out of 10 score on each - this will improve your knowledge and your chances of passing the 11-plus.
See how you get on with this quiz and when you feel confident, move onto the next one.

The weight of each apple 4,800 ÷ 12 = 400 g. You have to divide by 12 because you want to find out how many 'lots' of 12 there are in 4.8 kg: each 'lot' equals the weight of 1 apple: this is the same as adding 'lots' of 12 to itself until you get to 4,800 g

John will require 30 ÷ 3 = 10 pieces of fencing. You have to divide by 3 because you want to find out how many 'lots' of 3 there are in 30: each 'lot' equals the weight of 1 piece of fencing: this is the same as adding 'lots' of 3 to itself until you get to 30

The number of wheelbarrow loads of bricks = 1,500 ÷ 75 = 20. You have to divide by 75 because you want to find out how many 'lots' of 75 there are in 1,500: each 'lot' equals 1 wheelbarrow loads of bricks: this is the same as adding 'lots' of 75 to itself until you get to 1,500

It takes her 12 ÷ 4 = 3 hours. You have to divide by 4 because you want to find out how many 'lots' of 4 there are in 12: each 'lot' equals 1 hour: this is the same as adding 'lots' of 4 to itself until you get to 12. Alternatively, since 12 miles is 3 times more than 4 miles, then she must take 3 hours to cover 12 miles. It's up to you how you solve these problems BUT always show your workings
