4vir4ik [10]

Question

The exchange rate at the post office is £1=€1.17 how many euros will you get for £280

Answer:

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
