Hi,

Been trying to figure out how to make a cell show a ratio in the form of 1:X

1 being a member of staff, x being the unit of work.

What I've tried:

VBA
Code:
Function GCD(numerator As Integer, denominator As Integer)

<code>  If denominator = 0 Then
    GCD = numerator
  Else
    GCD = GCD(denominator, numerator Mod denominator)
  End If
End Function</code>
Alongside this in the cell:

=D5/GCD(C5:D5)&":"&C5/GCD(C5:D5)

That doesn't give what I want - it simply gives the lowest factors of each number in the ratio. I want it to be 1:X (1 being 1 member of staff).

In Column D I have the # of staff assigned.
In Column C I have the units of work to be assigned evenly to the staff.
In Column E I want the ratio of the above two (i.e. the # of staff fluxuates, and when I change it, I want it to
show the ratio of work spread among the new value when I change it; so 4 staff, 20 units = 1:5. I hire someone, I change it to 5 and it updates to 1:4).

How to create a cell-sized chart?
Tiny charts, called Sparklines, were added to Excel 2010. Look for Sparklines on the Insert tab.

Never mind.

Solved with:

=CONCATENATE("1:",(C5/D5))

Haha, that was way too simple xD!

What if you had 6 staff and 20 units? The ratio should be 3:10

This formula should give 3:10
=SUBSTITUTE(TEXT(C5/D5,"# ???/???"),"/",":")

It uses the fraction format to get the correct ratio then substitutes the "/" symbol with a colon :

If you are looking for a worksheet function how about this in cell E2 (or wherever the data starts):

="1" & ":" & ROUND((C2/D2),1) which gives the data below:

<TABLE style="WIDTH: 163pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=217 border=0><COLGROUP><COL style="WIDTH: 67pt; mso-width-source: userset; mso-width-alt: 3254" width=89><COL style="WIDTH: 48pt" span=2 width=64><TBODY><TR style="HEIGHT: 15pt" height=20><TD class=xl66 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; WIDTH: 67pt; BORDER-BOTTOM: windowtext 0.5pt solid; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" width=89 height=20>Units of work</TD><TD class=xl66 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; WIDTH: 48pt; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent" width=64># of staff</TD><TD class=xl66 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; WIDTH: 48pt; BORDER-BOTTOM: windowtext 0.5pt solid; BACKGROUND-COLOR: transparent" width=64>Ratio</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>20</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">5</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">1:4</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>10</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">3</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">1:3.3</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>40</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">4</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">1:10</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>15</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">6</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">1:2.5</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>16</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">6</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">1:2.7</TD></TR><TR style="HEIGHT: 15pt" height=20><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; HEIGHT: 15pt; BACKGROUND-COLOR: transparent" height=20>14</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">6</TD><TD class=xl65 style="BORDER-RIGHT: #ece9d8; BORDER-TOP: #ece9d8; BORDER-LEFT: #ece9d8; BORDER-BOTTOM: #ece9d8; BACKGROUND-COLOR: transparent">1:2.3</TD></TR></TBODY></TABLE>

column C contains the units of work, column D contains the # of staff, and column E contains the formula for the ratio. You can use the "Round", "Roundup", or "rounddown" functions depending on how you evaluate the need for more staff. You can also play with the number of digits in the round function.
