Question
The exchange rate at the post office is £1=€1.17 how many euros will you get for £280
Answer:
<h2>
327.6 €</h2>
Step-by-step explanation:
you can solve with an equation
1£ : 1.17€ = 280£ : x
1 : 1.17 = 280 : x
x = 1.17 * 280 : 1
x = 327.6
-------------------
check
1 : 1.17 = 280 : 327.6
0.85 = 0.85
the answer is good
------------------------------------
or you can simpy solve with a multiplication
280 * 1.17 = 327.6
Here are the steps
(4*3)+(4*-2x)=(4x)+(4*-6)
...12+-8x=16x-24x
...-8x+24x-16x=-12
0x=-12
x=-12/0
dividing by 0.
so there is no solution.
