The LCD of 3 and 4 is?

hellomynameiskam · Answer

3, 6, 9 , 12
4, 8 12

anonymous · Answer

So 12. Now, can you convert them to a denominator of 12?

skullpatrol · Answer

Are you sure option C is copied correctly.  It should be 2 5/12, which is the answer, not 2 5/10 which would be 2 1/2 :-)

hellomynameiskam · Answer

C was a typo.. sorry @skullpatrol and yes

anonymous · Answer

Uhh, I don't think skullpatrol has that correct

hellomynameiskam · Answer

for C i meant to put  2 5/12 not 2 5/10

anonymous · Answer

Ok, but I was referring to skullpatrolling's implication that 2 5/12 is the answer. That isn't right.

skullpatrol · Answer

Convert the mixed numbers into improper fractions and use the common denominator of 12, then subtract.

skullpatrol · Answer

10 2/3 = 32/3 = 128/12

8 3/4 = 35/4 = 105/12

128/12 – 105/12 = 23/12 = 1 11/12 in.
