To work this out, we need to figure out what 18.5÷8 is so we know how many times less soup there is.
The answer to 18.5÷8 is 2.3125
This means 18.5 is 2.3125 times bigger than 8, which also means that 524 will be 2.3125 times bigger than our answer.
To get that answer, all we have to do now is do 524÷2.3125 = 226.594594
To the nearest whole gram, the final answer comes to 223g
