I know £1 = ฿ 43.56 (Thai Baht) how would I work out how many pounds, 1000 Baht is? So to convert between £ and ฿ you need to ÷ 43.56 ÷ 43.56 £1 = ฿ 43.56 Convert the following amounts to British Pounds (GBP). a) 200 Bahtb) 1400 Bahtc) 70 Baht 1000 Baht ÷ 43.56 = £22.95684114 = £22.96 £4.59£32.14 £1.61 Lesson 7 Exchange Rates and Conversion graphs.
