Hi Mitch,
Let's work up to this.
^{10}/_{2} = ?? That's easy, the answer is 5 since 2 × 5 = 10. This answer makes me think that I can ask the question in a different way. Instead of ^{10}/_{2} = ?? I am going to ask What do you multiply the denominator by to get the numerator? Said in symbols 2 × ?? = 10.
Try another
Again I want to ask What do you multiply the denominator by to get the numerator? or
2 × ?? = ^{2}/_{7} . Now you can see ?? = ^{1}/_{7}
And one more
Reworded it becomes ^{1}/_{3} × ?? = 4 and hence ?? = 12.
Finally
Penny
