To find what K is, we have to use fractions. Since K is over 11, we have to convert 40 and 32 into fractions over 11. Multiply 40 by 11 to get 440. Multiply 32 by 11 to get 352, so your equation will now read:
440/11=k/11+352/11
When one part of an equation is a fraction, you need to make all parts of the equation into fractions. Now take all the top numbers to make a new equation, which reads:
440=k+352
440-352=k
k=88
Now we take our answer and put it back into the original equation to see if we were right.
40=88/11+32
40=8+32
40=40

40 - 32 = 18
18/11 = 0.5625
then to chek 11 * .7272 =8 8+32 =40
so k ~ 0.7273

40-32=k/11+32-32
k/11=8
k=8*11
k=88
been a lot of years since i've been in algebra classes, but i think i did that right.

first, let's rearrange the problem to make it easier:
k/11 + 32 = 40
k/11 = 8
k=88

subtract both sides by 32 then multiply both sides by 11.
