How does knowing the answer to a particular sum help you work out another
Question asked by: hmcpadden

It is not particularly helpful other than you know that 128/28 is 4.57... and therefore you can multiply the first number by that to get the answer to the second sum, but with something like that it's just as quick to do the simple sum each time without reference to the other.
