Q: Solve for h: 5h/7 = 5/14
A: The dreaded fraction haunts us again, huh?
5h/7 = 5/14
I am trying to get h by itself… Since the h is being divided by a 7, I am going to multiply everything by a 7 to get rid of it:
7*(5h/7) = 7*(5/14)
Now simplify:
35h/7 = 35/14
Reduce fractions:
5h = 5/2
Now, there is a 5 multiplying the h… SO, we need to divide everything by 5. But wait… Does this will give us 5/2 divided by 5… ACK! A fraction inside of a fraction. This is definitely do-able, but not the easiest. So, instead of dividing by 5, I am going to multiply everything by 1/5 (this is essentially the same thing). Watch:
5h = 5/2
(1/5)*5h = (1/5)*5/2
Multiply fractions across the top and across the bottom to get:
5/5 * h = 5 / 10
reduce:
h = 1/2
There it is.
