*FRACTION PROBLEM*

When adding fractions, you need a common denominator. Convert fourths and eighths to sixteenths.

okay, i know this is a simple math problem, but can you guys please explain how 38 7/16 is the answer. Im getting 37 13/16.

12 9/16+ 17 3/4+ 8 1/8= 38 7/16

can you guys explain this problem step by step! thanks

ok, since you did the work...

the common denominator is 16, right? meaning the 4, the 8 and the 16 are all divisible by 16....

so, that makes

12 9/16 + 17 3/4 + 8 1/8 =

12 9/16 + 17 12/16 + 8 2/16 .....right?

9/16 + 12/16 + 2/16 = 23/16

23/16 = 1 7/16

12 + 17 + 8 + 1 7/16 = 38 7/16

I think you were leaving out the 1 from figuring 23/16 = 1 7/16

wait, we cross posted....


when you find the common denominator, you have to multiple whatever you multipled the denominator by to get the new neumerator.

for intance....if you had 1/6 and 1/18....

finding the common denominator of 18, does not make it equal to

1/18 + 1/18.....is does make it equal to

3/18 + 1/18 (you had to multiple the 6 by 3 to get 18, so you have to multiple the 1 by 3 also)

wait, we cross posted....

I GOT YA! thank yo so much, i was going crazy. so basically since 16 is the common denominator, i figure out how times does the previous denominator goes into 16 right? okay

You're late to the party, Francis.

If that doesn't make sense, let's pick a really simple example....


ok, you know that 5/10 equals 1/2, right? Also, 8/16 = 1/2, 20/40 = 1/2, etc....

so, if you had 5/10 and 1/2.....you know the common denominator is 10....right?

but, it wouldn't make sense to then say 5/10 and 1/10.....because you know 1/10 does NOT equal 1/2 of something.

so, since you had to multiple the 2 in 1/2 by 5, to get the 10....you ALSO have to multiple the 1 in 1/2 by 5 to make it 5....so, you get 5/10.

it's like saying 1/2 x 5/5

1/2 x 5/5 = 5/10.

5/5 = 1, so you can multiple it by 1/2 and it will not change the value.

*****What you do to the denominator, you must also do to the numerator.*****

hey kid, go....get out of here.

I'll have hell to pay the rest of the night here....you...go back to school, make something of yourself.

remember me....you'll be my only legacy.
