Answer:
Step-by-step explanation:
SGD / USD * USD / AUD = SGD/AUD
Now put in the numbers :
1 /.74 * .71 / 1 = 71/74 SGD /AUD
THEN just flip it: 74/71 AUD/SGD = 1.042 AUD/SGD
25000 AUD * 71/74 SGD/AUD = 23986 SGD
Answer:
(a) 1 AUD = 0.959 SGD
(b) 25,000 AUD = 23,986 SGD
Step-by-step explanation:
We have the following exchange rates
0.74 USD = 1 SGD
This means
[tex]1 $ USD = $ \dfrac{1}{0.74} $ SGD (divide both sides by 0.74)[/tex]
0.71 USD = 1 AUD
[tex]1 $ USD = $ \dfrac{1}{0.71} $ AUD (divide both sides by 0.71)[/tex]
(a)
Therefore
[tex]1 $ USD = $ \dfrac{1}{0.74} $ SGD = \dfrac{1}{0.71} $ AUD[/tex]
or
[tex]\dfrac{1}{0.74} $ SGD = \dfrac{1}{0.71} $ AUD[/tex]
Switch sides:
[tex]\dfrac{1}{0.71} $ AUD = \dfrac{1}{0.74} $ SGD[/tex]
Multiplying both sides by 0.71 gives
[tex]1 $ AUD = \dfrac{1}{0.74} \cdot 0.71 = \dfrac{0.71}{0.74} = 0.959 $ SGD[/tex]
(b) If the remittance is 25,000 AUD then the amount in SGD = 25,000 x 0.959 = 23,986 SGD
