Rice costs £3 for a 500g packet. How much for 4 1/2kg of rice?

Answer 1

We need to first convert 4 1/2 kilograms to grams, as the price is given for 500g:

4.5kg = 4500g

Now we can find the cost of 4500g of rice:

Cost of 500g of rice = £3

Cost of 1g of rice = £3/500

Cost of 4500g of rice = (Cost of 1g of rice) x 4500

Cost of 4500g of rice = (£3/500) x 4500

Cost of 4500g of rice = £27

Therefore, the cost of 4 1/2kg of rice is £27.
