The standard golf ball has a mass of 45g. How many golf balls are there in a bag weighing 1.8kg?
2 answers:
This is a working backwards question.
Since the golf ball was 45g, and the bag was 1.8kg,we need to make them the same units.
45g= 0.45kg
1.8kg= 1.8kg
Now that the units are the same, we put it in a calculator.
1.8÷0.45= 4
Therefore, there are 4 golf balls in the bags.
We can check this by doing 4×0.45= 1.8

To show that a statement is true, you need evidence.
Take for instance:
The evidence that the above proof is true is by taking the <em>squares of both sides of </em>
However, a counterexample does not need a proof per se.
What a counterexample needs is just an instance or example, to show that:
An instance to prove that: is false is:
Hence, the complete statement could be:
<em>In a direct proof, evidence is used to support a proof . On the other hand, a counterexample is a single example that shows that a proof is false.</em>
