use fraction bars to help:
a) 11/12=w+y
b)3/8=3/6-k
c)1/4=n-7/12
d) how many 1/12's are in 1 1/4?
help! im sooooooo..... confused!
for d) put 1 1/4 into an improper fraction. That would be 5/4. Follow so far? Then cross multiply 5/4 and x/12. So, 4x = 5(12). from here just solve for x.
what is the question for a)? In b), first add k to both sides to get 3/8 + k = 3/6. Then you have to subtract 3/8 from each side. The common denominator is 24, so 3/6 - 3/8 becomes 12/24 - 9/24 which equals 3/24, or 1/8. For c), you must add 7/12 to each side. The common denominator of 4 and 12 is 12 so 1/4 + 7/12 becomes 3/12 + 7/12 which equals 10/12, or 5/6.
