Question

David drew a double number line diagram and stated that 50% of 36 is 16. Is he correct?

Answer 1

The claim we need to check is that 16 is the 50% of 36.

Recall that if we add 50% and 50%, we should end up with 100%. In our case, we have that our 100% is 36. So, if it was true that 16 is the 50% of 36, then it should happen that if we add 16 with itself, we should get 36.

Note that

$16+16=32$

Since 16+16 is not 36, it is not true that 16 is the 50% of 36.
