With great difficulty. The easy bit was shillings: there were 20 shillings in a pound and 100 decimal pennies. At the time of their introduction, the latter were called New Pence (NP) and I will stick to that notation.So 1 shilling = 0.05 pounds = 5 NP.
The problem came with converting 12 [old] pennies in a shilling to 5 NP. A saving grace was that there was still a 1/2 New Penny coin
Formally, that was done though rounding:
1p = 0.41666... NP
2p = 0.83333... NP
3p = 0.1.25 NP
4p = 0.16666... NP
5p = 2.08333... NP
6p = 2.5 NP
7p = 2.91666... NP
8p = 3.33333... NP
9p = 3.75 NP
10p = 4.1666... NP
11p = 4.5833... NP
12p = 5.0 NP
Conversion tables were published but I am sure that many people were ripped off before the transition settled down.
All school kids got used to it very quickly. The maths of predecimal currencies was another reason for the conversion to a decimal based currency system. There were 12 Pennies in a Shilling, and 20 Shilling in a Pound. That is what you need to remember. Add these two predecimal values - £3/15/6 - 3 Pounds, 15 Shillings and 6 Pence. £2/ 7/ 8 - 2 Pounds, 7 Shillings and 8 Pence. Add the pennies first. 8 Pence + 6 Pence = 14 Pence. 14 Pence = 1 Shilling and 2 Pence. Put down the 2 Pence and carry the 1 Shilling. £ / / 2 Next, add the Shillings starting with the carried over 1 Shilling from the Pence addition. 1 Shilling + 7 Shillings + 15 Shillings = 23 Shillings. 23 Shillings = 1 Pound and 3 Shillings. Put down the 3 Shillings and carry the 1 Pound. £ / 3/ 2 Finally, add the Pounds starting with the carried over 1 Pound from the Shillings addition. 1 Pound + 2 Pound + 3 Pound = 6 Pounds. £6/ 3/ 2 - Total = 6 Pounds, 3 Shillings and 2 Pence. Easy. This was mental arithmetic for shopkeepers and other business people in predecimal days.

Well, darling, 5 pence is worth about 7 cents in American money, and 6 pence is worth about 9 cents. So, if you add those together, you've got yourself a whopping 16 cents. Not exactly enough to buy you a fancy latte, but hey, every penny counts!
LSD in British pre-decimal currency stands for pounds, shillings, and pence. It was the system used in Britain before decimalization in 1971, where there were 12 pence in a shilling and 20 shillings in a pound.
Pounds, Shillings and Pence. Pre-decimal.
On "Decimal Day" in 1971, Ten Shillings converted to 50 New Pence. Ten Shillings was equal to 120 old Pence.
In the old currency, there were 12 Pence in a Shilling and 20 Shillings in a Pound. At Britains conversion to decimal, One Pound changed from One Pound of 240 (old) Pence, to One Pound of 100 (new) Pence. Ten Shillings became 50 New Pence Two Shillings became 10 New Pence One Shilling became 5 New Pence Later on, two further coins were introduced - 25 (New) Pence was the equivalent of the old Crown (Five Shillings) 20 (New) Pence was equivalent to 4 Shillings. There was no new decimal coin for the other old denominations. A Halfcrown converted to 12.5 New Pence Sixpence converted to 2.5 New Pence Threepence converted to 1.25 New Pence One old Penny converted to 0.416 New Pence One old Halfpenny converted to 0.208 New Pence
110 British Pence = One Pound and Ten Pence in the new currency. In the old British currency, it would be 9 Shillings and Twopence (9/2d).
You seem to have answered your own question. If you're trying to convert shillings and sixpence into modern pence, it becomes 17 pounds and 47.5 pence.
The Sovereign face value = 1 Pound or 20 Shillings - now 1 Pound The Half-Sovereign face value = 10 Shillings - now 50 Pence The old Crown of Five Shillings = 25 Pence The Halfcrown = 12.5 Pence The Florin of Two Shillings = 10 Pence The Shilling = 5 Pence The Sixpence = 2.5 Pence The Threepence = 1.25 Pence The old Penny = 0.416 Pence The old Halfpenny = 0.208 Pence The Farthing = 0.104 Pence
24 pence. In pre-decimal currency in the UK it was 24 old pence. The equivalent today would be 10 pence.
360 "old" pence was equivalent to £1/10/-, or One Pound, Ten Shillings. At decimalisation, One Pound became 100 "New" Pence and Ten Shillings became 50 "New" Pence. 360 "old" Pence converted to 150 "New" Pence or £1.50 in decimal currency.
One shilling is equivalent to 5p (five pence) in decimal currency. Before decimalisation the currency was in pounds, shillings and pence. There were twelve pennies to a shilling and twenty shillings in a pound. On "Decimal Day" (15 February 1971) pennies and shillings were replaced by the new currency with 100 new pennies in a pound.
One pre-decimal pound was 20 shillings, one shilling was 12 pence, so one pound was 240 pence.
The shilling was used in the former British monetary system of Pounds - Shillings - Pence (the "Lsd system"), which was replace in 1968 by the current decimal system (100 pence to the Pound). Under the Lsd system, there were 20 shillings to the Pound and 12 pence to the shilling. Shillings are also used as the principal unit of currency in Kenya and Somalia, and the Schilling was used in Austria.
