Question

Anyone know the answer

Answer 1

Hello there,

So what we need to find how many number of costumes that can be made using ONLY 11$\frac{1}{4}$.

The first thing we would do is $\frac{3}{4}$÷11$\frac{1}{4}$. 

Your answer this this would be $\frac{1}{15}$.

To recheck this. . . We do $\frac{1}{15}$ x $\frac{3}{4}$. . .

Your answer would be 11$\frac{1}{4}$.

That is how you recheck your work.

Your correct answer would be $\frac{1}{15}$

Hope this helps! :)

Answer 2

turn 11 1/4 into an improper fraction:

11 1/4 = 45/4

 now you have 3/4c = 45/4

now divide both sides by 3/4

c = 45/4 / 3/4 which =  45/4 * 4/3 = 180/12 = 15

15 costumes can be made
