Think not in integers?

Question

Easier again:

Make 24 using only the digits 1, 4, 5 and 6, with the following conditions:

They should not be clubbed /joined (to form such as 64 or 51 etc.)
Only the basic arithmetic operations (+, -, * and /) are allowed to be performed. (Means - No use of powers / roots / factorials etc.)
All the given digits should be used and
All the given digits should be used only once

@bleh No, ${1,3,4,6}\neq{1,4,5,6}$. – Rand al'Thor Jul 18 '17 at 17:18 — Rand al'Thor, Jul 18 '17 at 17:18

If this is easy as I think it is

$6/(5/4-1)$

Which simplifies to

$6*4$

Which is 24

Or you can do it the other way...

$4/(1-5/6)$

Which simplifies to

$4*6$

Well, good work @bleh (fast enough), though there is another way to achieve the same (can be considered as a bonus !) – Mea Culpa Nay Jul 18 '17 at 15:51
Yes, @bleh, you got the other one also correct ! – Mea Culpa Nay Jul 19 '17 at 05:13

The answer for this is very similar to the answer here https://puzzling.stackexchange.com/a/1641/10399

$\dfrac{6}{\frac{5}{4} - 1}$.

This simplifies to $\frac{6}{1/4}$, which becomes $6 \cdot 4$, which becomes $24$.

You should probably checkmark @bleh's answer. I literally just copy-pasted mine and changed the first formula a bit to match your inputs. – Ian MacDonald Jul 18 '17 at 15:59
