You would solve that problem like this:
1. Convert the number to an improper fraction: 3 7/16 = 48/16 + 7/16 = 55/16

2. Since numerator is an odd number, it won’t divide by 2 as is, so multiply top and bottom of the fraction by 2: 55/16 = 110/32.

3. Fraction can now be divided by 2: 110/32 divided by 2 = 55/32.

4. Convert number back to a proper fraction: 55/32 = 1 23/32.

That's all there is to it.

if you have a mixed fractional number, the easiest way is to turn it into a complete fraction...

3 7/16

multiply the 3 by 16 getting 48

add that to the top 48 + 7 getting 55

you now have 55/16

multiply the bottom by 2 getting 55 / 32

change it back into a mixed fraction; divide the top number by the bottom.

it becomes 1 23/32

There are other ways, but I think this is the cleanest.

First, the 7/16. The 7 is the problem. We need to change the fraction to an equivalent fraction. Easily done by doubling BOTH the top and the bottom of the fraction. So we get 14/32. To divide this by 2 is easy, half of 14/32 is 7/32.

The 3 needs to be divided in two as well. This is 1 1/2, but we could do with this in 32nds too. It's 1 16/32 (since 16/32 is just 1/2)

Add the 7/32 and the 1 16/32 and we have 1 23/32.

There you go...

1 = 16/16. You have 3 which is 48/16. Plus another 7/16 which makes a total of 55/16.

Divide 55 by 2, equal 27 1/2

So each half is 27.5 / 16 large

reduce that (convert the fraction) to 1 9.5/16 or just under 1 5/8

to be real picky lets convert 16ths to 32nds

1 9.5/16 = 1 19/32

That's the exact number you need.

bear with me..... the president says "... i don't want to be in the car business...." give the stock to the people who paid fot it, taxpayers, NOT on the government dole(i.e. welfare, morgage bail out, etc, etc)

this accomplishes several things, obama is outta the car business, people with a share of stock will be more inclined to buy GM cars, the free market system is put back in place, the people decide what cars Gm makes, not the sierra club, and we get what WE paid for, and the government doesn't get a chance to screw things up.
