The exchange rate at a post office is £1 = 1.17 euros <br><br> how many euros will u get for £280

Sati [7]

Answer:

327.6 €

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

1/2 + 1/3 - 1/4 = I don't know

Use "PEMDAS"
First we'll add then subtract

$\frac{1}{2} + \frac{1}{3} = \frac{2}{6} + \frac{2}{6} = \frac{4}{6}= \frac{2}{3}$

$\frac{2}{3} - \frac{1}{4} = \frac{8}{12} - \frac{3}{12} = \frac{5}{12}$

$\frac{1}{2} + \frac{1}{3} - \frac{1}{4} = \frac{5}{12}$
