Answer 1

Answer:

Option C. 12.50 Danish kroner

Step-by-step explanation:

It is given that Foreign exchange rate between the U.S. dollar and the Danish kroner is 1 : 2.50

We have to calculate how many Danish kroner in 5 dollar, so we multiply 2.50 with 5.

∵ 1 dollar = 2.50 Danish kroner

∴  5 dollar = 2.50 × 5 = 12.50 Danish Kroner

Option C. 12.50 Danish kroner

Answer 2

$\bf \begin{array}{ccll} US~\ &Danish~\ \\ \cline{1-2} 1&2.50\\ 5&d \end{array}\implies \cfrac{1}{5}=\cfrac{2.50}{d}\implies d=\cfrac{5\cdot 2.50}{1}\implies d=12.5$
