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.

To clarify, it seems like you have provided several statements without clear questions for some of them. I'll try to help you with what I understood so far.
a) Statement: 11/12 = w + y
b) Statement: 3/8 = 3/6 - k
c) Statement: 1/4 = n - 7/12
d) Question: How many 1/12's are in 1 1/4?
Let's go step by step:
a) In this equation, you need to find the values of w and y when 11/12 is equal to their sum. To represent this visually, you can use fraction bars. Draw a whole bar, divided into 12 equal parts. Shade 11 of those parts to represent 11/12. Now you need to find the values of w and y that will fill up the remaining unshaded parts.
b) Here, you need to find the value of k that satisfies the equation. To visually represent this using fraction bars, you can draw two separate bars, each divided into 6 parts. Shade 3 of the parts on the left bar to represent 3/6, which is equal to 1/2. Now you need to find the value of k that results in 3/8 when subtracted from 1/2. Visualize this by changing 1/2 on the left bar to 4/8, then subtracting 3/8 from it. Shade the remaining 1/8 to represent the value of k.
c) For this equation, you need to find the value of n when n minus 7/12 is equal to 1/4. To represent this visually, draw a bar divided into 12 parts. Shade 7 of those parts to represent 7/12. Visualize n by adding 1/4 to the shaded part, resulting in a total of 10/12 being shaded.
d) To find how many 1/12's are in 1 1/4, we need to convert 1 1/4 into an improper fraction. Multiply the whole number (1) by the denominator of the fraction (4) and add the numerator (1), which gives us 5. Now write 5/4. To find how many 1/12's are in this fraction, you can set up a proportion with x/12 = 5/4. Cross multiplying gives you 4x = 5 * 12. Solve for x, and you'll find how many 1/12's are in 1 1/4.
